      spl/85xx: new SPL support · c97cd1ba
      由 Scott Wood 提交于 
      Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL
and CONFIG_SPL_BUILD, respectively.  CONFIG_NAND_SPL can be removed once
the last mpc85xx nand_spl target is gone.

CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does.  Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
(necessarily) ramboot, and we don't have separate configs for SPL and
main u-boot.  It was also inconsistent, as other platforms such as
mpc83xx didn't use CONFIG_RAMBOOT in this way.

      spl/mpc85xx: move udelay to cpu code · 59629c28
      由 Scott Wood 提交于 
      It applies to non-Freescale 85xx boards as well as Freescale boards,
so it doesn't belong in board/freescale.  Plus, it needs to come out
of nand_spl if it's to be used by the new SPL.

      powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxx · 8bc50f0b
      由 Scott Wood 提交于 
      It's arch code and not a driver, so move it where it belongs.  When it
originally went into drivers/misc there was no 8xxx CPU directory.

This will make new-SPL support a little easier since we can keep the CPU
stuff together and not need to pull stuff in from drivers/misc.

      powerpc/mpc85xx: fix TLB alignment · 7f0a22ff
      由 Scott Wood 提交于 
      In the RAMBOOT/SPL case we were creating a TLB entry starting at
CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly
aligned for the TLB entry size.  This turned out to not be the case
with NAND SPL because the main U-Boot starts at an offset into the image
in order to skip the SPL itself.

Fix the TLB entry to always start at a proper alignment.  We still assume that
CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary
thus requiring multiple TLB entries.

      powerpc: change .fixup test to a GCC version test · 6ec63f41
      由 Scott Wood 提交于 
      This was introduced by commit 24461519, but it
fails in a minimal SPL build where the only thing in arch/powerpc/lib is
cache.c, which apparently doesn't generate any fixup records.

The problem is reported to occur with GCC 3.x, so insist on GCC 4.0 or newer.
Patterned after checkthumb as suggested by Tom Rini.

      spl: introduce CONFIG_SPL_TARGET · ca2fca22
      由 Scott Wood 提交于 
      Currently the SPL target is specified in a CPU-specific makefile
fragment.  While some targets may need something more complicated than a
simple target name, targets which don't need this shouldn't have to provide a makefile fragment just for this.

      由 Scott Wood 提交于 
      Previously, in many if not all configs we were creating overlapping TLB entries
which is illegal.  This caused a crash during boot when moving p2020rdb NAND SPL

      serial/ns16550: wait for TEMT before initializing · cb55b332

      TEMT is set when the transmitter is totally empty and all output has
finished.

This prevents output problems (including a loss of synchronization
observed on p2020 that persisted for quite a while) if SPL has output
still on its way out.

      serial/ns16550: don't build serial_ns16550 with MIN_FUNCTIONS · 48cbc3a8
      由 Scott Wood 提交于 
      CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic
ns16550 output code without pulling in things not needed by the SPL.

This previously only worked with non-MULTI configs.  Recently MULTI was
made mandatory, and MIN_FUNCTIONS fails like this:

drivers/serial/libserial.o: In function `calc_divisor.clone.0':
serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq'
drivers/serial/libserial.o: In function `_serial_getc':
(.text._serial_getc+0x30): undefined reference to `NS16550_getc'
drivers/serial/libserial.o: In function `_serial_tstc':
(.text._serial_tstc+0x30): undefined reference to `NS16550_tstc'
drivers/serial/libserial.o: In function `_serial_setbrg':
(.text._serial_setbrg+0x3c): undefined reference to `NS16550_reinit'
make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1
make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2

With MIN_FUNCTIONS we don't need anything from this file, so don't build
it.  The conditional needs to be in the file itself rather than the
makefile, because the config symbols are only imported to the makefiles
once, not separately for the SPL phase of the build.
