      BOOT: Add "bootz" command to boot Linux zImage on ARM · 44f074c7
      由 Marek Vasut 提交于 
      This command boots Linux zImage from where the zImage is loaded to. Passing
initrd and fdt is supported.

Tested on i.MX28 based DENX M28EVK
Tested on PXA270 based Voipac PXA270.

NOTE: This currently only supports ARM, but other architectures can be easily
added by defining bootz_setup().

      arm: Use common .lds file where possible · 4a076485
      由 Simon Glass 提交于 
      Each cpu directory currently has its own .lds file. This is only needed
in most cases because the start.o file is in a different subdir.

Now that we can factor out this difference, we can move most cpus over
to the common .lds file.

      arm: add a common .lds link script · dde3b70d
      由 Simon Glass 提交于 
      Most ARM CPUs use a very similar link script. This adds a basic
script that can be used by most CPUs.

Two new symbols are introduced which are intended to eventually be
defined on all architectures to make things easier for generic relocation
and reduce special-case code for each architecture:

__image_copy_start is the start of the text area (equivalent to the
existing _start on ARM). It marks the start of the region which must be
copied to a new location during relocation. This symbol is called
__text_start on x86 and microblaze.

__image_copy_end is the end of the region which must be copied to a new
location during relocation. It is normally equal to the start of the BSS
region, but this can vary in some cases (SPL?). Making this an explicit
symbol on its own removes any ambiguity and permits common code to always
do the right thing.

This new script makes use of CPUDIR, now defined by both Makefile and
spl/Makefile, to find the directory containing the start.o object file,
which is always placed first in the image.

To permit MMU setup prior to relocation (as used by pxa) we add an area
to the link script which contains space for this. This is taken
from commit 7f4cfcf4. CPUs can put the contents in there using their
start.S file. BTW, shouldn't that area be 16KB-aligned?

      arm: Remove unneeded setting of LDCSRIPT · 9492791a
      由 Simon Glass 提交于 
      This is set by the top level Makefile anyway, so drop it. This does
have the effect of changing the order - now the board link script will
have preference over the CPU one. But this seems more correct anyway.
