9e02a6b8e5 arm: restore fdt_fixup_ethernet call to do_bootm_linux
Commit 0a672d4 "arm: Add Prep subcommand support to bootm" re-organized
do_bootm_linux for ARM. During the re-organization, the call to
fdt_fixup_ethernet() was removed. I assume this was useful, so add it
back.

1723997610 arm: fix bootm with device tree
Commit 0a672d4 "arm: Add Prep subcommand support to bootm" re-organized
do_bootm_linux() for ARM. During the re-organization, the code to pass
the device tree to the kernel was removed. Add it back. This restores
the ability to boot a kernel using device tree.

44f074c771 BOOT: Add "bootz" command to boot Linux zImage on ARM
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().

f933e84e34 bootstage: arm: Add bootstage calls in board and bootm
Add calls to bootstage before and after relocation, and just
before jumping to the OS.

The idea here is you can call bootstage_report() to get a report.
Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is
printed automatically by U-Boot just before jumping to the kernel.

953209bf5e arm: add __aeabi_unwind_cpp_pr1() function to avoid linker complaints
With the ELDK 5.1 (beta) "armv7a" toolchain I'm get the following
build failure:

  $ ./MAKEALL mx51evk
  ...

  make: *** [u-boot] Error 1

This patch fixes the issue similar to commit
d442b6e7ad6a86e2fd0e6297291fe8872ff26fc6 but I don't know if it's
general enough or if it does harm when using other toolchains.

bc4e14c43c arm: Correct build error introduced by getenv_ulong() patch
Commit dc8bbea removed a local variable that is used in most ARM boards.

Since we want to avoid an 'unused variable' warning with later compilers,

this declares the variable local to the block of code that needs it.

d8834a1323 arm: Use optimized memcpy and memset from linux
Using optimized versions of memset and memcpy from linux brings a quite
noticeable speed (x2 or better) improvement for these two functions.

Here are some numbers for test done with jadecpu

55b0a39314 Respect memreserve regions specified in the device tree
If a regions is reserved in the fdt, then it should not be used.  Add
the memreserve regions to the lmb so that u-boot doesn't use them to
store the initrd.

590d3cacb9 Stop passing around bootmem_base value.
For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low().  Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.
