The USB boot code is too fat and complicated to be included in SPL
(at least for now).  So, it was implemented as a separate project
(what we call USB-loader).

The expected boot sequence is as follows:

  Boot ROM -> USB-loader -> SPL -> U-Boot proper

The USB-loader loads the SPL and U-Boot proper from a USB memory
onto the locked L2 cache.  Then, SPL needs to copy the U-Boot proper
to DRAM, so this mode looks like a NOR boot from the view of SPL.
However, we want to distinguish between (genuine) NOR boot and USB
boot in some places.

UniPhier SoCs are not equipped with dedicated on-chip SRAM.  Instead,
locked outer cache is used as RAM area during the early boot stage
where DRAM is not ready yet.  This effectively means MMU must be
always enabled while we are in SPL.

Currently, the SPL image for UniPhier SoCs contains the page table
statically defined at compile time.  It has been a burden because the
16KB page table occupies a quarter memory footprint of the 64KB SPL
image.

Finally, there is no more room to implement new features in SPL.
Setting aside the NOR boot mode, this issue can be solved by creating
the page table onto RAM at run time.

No special reason for the current stack address 0x0ff08000.
Change it to 0x00100000 to simplify the init_page_table.

There are two types of SoCs in terms of the load address of SPL.

 [1] PH1-sLD3, PH1-LD4, PH1-sLD8
   SPL is loaded at 0x00040000-0x0004ffff
 [2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b
   SPL is loaded at 0x00100000-0x0010ffff

The new stack area (0x000f8000-0x00100000) should be safe for all the
cases.

Since commit ad1ecd20 ("fdt: Build a U-Boot binary without device

device tree"), we can use shorter file names for the output images.

The default configuration for UniPhier SoCs enables CONFIG_OF_SEPARATE
and CONFIG_SPL_OF_CONTROL.  In this case, spl/u-boot-spl.bin is the
same as spl/u-boot-spl-dtb.bin.  Likewise, u-boot.img is the same as
as u-boot-dtb.img.  So, this change of the flow has no impact.

Implement three improvements to the HTML log file:
- Ability to expand/contract sections. All passing sections are contracted
  at file load time so the user can concentrate on issues requiring
  action.
- The overall status report is copied to the top of the log for easy
  access.
- Add links from the status report to the test logs, for easy navigation.

This all relies on Javascript and the jquery library. If the user doesn't
have Javascript enabled, or jquery can't be downloaded, the log should
look and behave identically to how it did before this patch.

A few notes on the diff:

- A few more 'with log.section("xxx")' were added, so that all stream
  blocks are kept within a section block for consistent HTML entity
  nesting structure. This changed indentation in a few places, making
  the diff look slightly larger.
- HTML entity IDs are cleaned up. We assign simple incrementing integer
  IDs now, rather than using mangled test names which were possibly
  invalid.
- Sections and streams now use common CSS class names (in addition to the
  current separate class names) to more easily share the new behaviour.
  This also reduces the CSS file size since rules don't need to be
  duplicated.
- An "OK" status is logged after some external command executions so that
  make and flash steps are auto-contracted at log file load time, assuming
  they passed.

On some systems, RAM starts at address 0. If the user executes itest
against address 0 on such a system, it will call map_physmem(0, ...)
which will return 0 back; mapping only changes the address on sandbox.
This causes itest to believe map_physmem() has failed, and hence fails
the comparison.

Fix itest so that it allows map_physmem() to return 0 /if/ the orignal
address passed to it was also 0.

This fixes "tegra-uboot-flasher flash" on Tegra20.

This has the disadvantage that on sandbox, failed mapping attempts for
address 0 are not detected. Instead, should the code only call
map_physmem() on sandbox? Or, should map_physmem() return its error status
some other way. Or, should the special case only be allowed on systems
where the base of RAM is 0 somehow?

Current, the following passes:
    ./u-boot -d arch/sandbox/dts/test.dtb -c 'ut_image_decomp'
but the following fails:
    ./u-boot -d arch/sandbox/dts/test.dtb -c 'ut dm; ut_image_decomp'

This is because the gunzip code reads input data beyond the end of its
input buffer. In the first case above, this data just happens to be 0,
which just happens to trigger gzip to signal the error the decompression
unit test expects. In the second case above, the "ut dm" test has written
data to the accidentally-read memory, which causes the gzip code to take a
different path and so return a different value, which triggers the test
failure.

The cause of gunzip reading past its input buffer is the re-calculation of
s.avail_in in zunzip(), since it can underflow. Not only is the formula
non-sensical (it uses the delta between two output buffer pointers to
calculate available input buffer size), it also appears to be unnecessary,
since the gunzip code already maintains this value itself. This patch
removes this re-calculation to avoid the underflow and redundant work.

The loop exit condition is also adjusted so that if inflate() has consumed
the entire input buffer, without indicating returning Z_STREAM_END (i.e.
decompression complete without error), an error is raised. There is still
opportunity to simplify the code here by splitting up the loop exit
condition into separate tests. However, this patch makes the minimum
modifications required to solve the problem at hand, in order to keep the

diff simple.

I am not entirely convinced that the loop in zunzip() is necessary at all.
It could only be useful if inflate() can return Z_BUF_ERROR (which
typically means that it needs more data in the input buffer, or more space
in the output buffer), even though Z_FINISH is set /and/ the full input is
available in the input buffer /and/ there is enough space to store the
decompressed output in the output buffer. The comment in zlib.h after the
prototype of inflate() implies this is never the case. However, I assume
there must have been some reason for introducing this loop in the first
place, as part of commit "Fix gunzip to work for any gziped uImage size".

This patch is similar to the earlier b75650d8 "gzip: correctly
bounds-check output buffer", which corrected a similar issue for
s.avail_out.

The ARM Linux kernel requires the DT to be in memory accessible early
during the boot process. This always happens naturally on the RPi 1,
since the maximum memory size of 512MiB, and additionally some of that
is reserved for use by the GPU. The RPi 2 has 1GiB of RAM (minus some
GPU usage), and so if the DT is relocated to the top of RAM, Linux cannot
access it. Prevent this from happening by setting fdt_high.

Implement command--line option --gdbserver COMM, which does two things:

a) Run the sandbox process under gdbserver, using COMM as gdbserver's
   communication channel.

b) Disables all timeouts, so that if U-Boot is halted under the debugger,
   tests don't fail. If the user gives up in the middle of a debugging
   session, they can simply CTRL-C the test script to abort it.

This allows easy debugging of test failures without having to manually
re-create the failure conditions. Usage is:

Window 1:
./test/py/test.py --bd sandbox --gdbserver localhost:1234

Window 2:
gdb ./build-sandbox/u-boot -ex 'target remote localhost:1234'

When using this option, it likely makes sense to use pytest's -k option
to limit the set of tests that are executed.

Simply running U-Boot directly under gdb (rather than gdbserver) was
also considered. However, this was rejected because:

a) gdb's output would then be processed by the test script, and likely
   confuse it causing false failures.

b) pytest by default hides stdout from tests, which would prevent the
   user from interacting with gdb.

   While gdb can be told to redirect the debugee's stdio to a separate
   PTY, this would appear to leave gdb's stdio directed at the test
   scripts and the debugee's stdio directed elsewhere, which is the
   opposite of the desired effect. Perhaps some complicated PTY muxing
   and process hierarchy could invert this. However, the current scheme
   is simple to implement and use, so it doesn't seem worth complicating
   matters.

c) Using gdbserver allows arbitrary debuggers to be used, even those with
   a GUI. If the test scripts invoked the debugger themselves, they'd have
   to know how to execute arbitary applications. While the user could hide
   this all in a wrapper script, this feels like extra complication.

An interesting future idea might be a --gdb-screen option, which could
spawn both U-Boot and gdb separately, and spawn the screen into a newly
created window under screen. Similar options could be envisaged for
creating a new xterm/... too.

--gdbserver  currently only supports sandbox, and not real hardware.
That's primarily because the test hooks are responsible for all aspects of
hardware control, so there's nothing for the test scripts themselves can
do to enable gdbserver on real hardware. We might consider introducing a
separate --disable-timeouts option to support use of debuggers on real
hardware, and having --gdbserver imply that option.

The recent change to memalign() caused the allocation failure detection
code to be dead code; the "retry" logic is always activated under the same
condition that the original failure detection code is, and also fully
handles any possible failures. This patch solves the presence of dead
code.

Two alternatives are possible:

a) Delete the now-dead test, and rely on the "retry" path to handle any
allocation problems, as it does.

b) Make the "retry" path fall through to the existing (currently dead)
failure detection code, thus making it not-dead.

(b) was chosen since it reduces the diff between U-Boot's and the upstream
dlmalloc. This should make it marginally easier to import a new version of
dlmalloc in the future.
