88fa0a6eb9 x86: Remove usage of %ebp as a return pointer
Using %ebp as a return pointer prevents creating 'load anywhere' images

00940a229d x86: Move ECC initialisation outside RAM initialisation
To allow for 'load anywhere' images, the %ebp return pointer 'hack' must
be removed, so we cannot have two 'calls' to get_mem_size

5c161653db x86: Change compiler options
Change to:

 - no-stack-protector
 - preferred-stack-boundary=2

These options make the code a little smaller and faster

abe98f49e1 x86: zboot update

5d7c73e65b ppc4xx: Use common ns16550 functions in 4xx UART POST driver
This patch changes the PPC4xx POST UART driver to use the common
NS16550 functions for receiving and sending. Additionally the
local function for SoC divisor setup are removed. Instead the
functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This
removes code duplication.

Also the common CONFIG_SYS_NS16550_COMx defines are now used
to describe the POST UART's.

And a compile breakage is fixed, introduced by a git merge of
the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to
"asm/ppc4xx.h". Fixed as well with this patch.

2778a01431 ppc4xx/fdt/flash: Fix bug in fdt_fixup_nor_flash_node()
This patch fixes a bug in fdt_fixup_nor_flash_node() when the reg
property has multiple reg tuples, like:

	reg = <0 0x00000000 0x04000000
	       0 0x04000000 0x04000000>;

In this case this function did not update the reg property correctly.

48c00fe25c Blackfin: propagate target cpu defines when building embedded env
Since we're no longer extracting the env from the target ELF file (since
upstream wouldn't take that change), we're back to the problem of cpu
defines not properly propagating to the env setup stage.  So the embedded
env built by the host compiler doesn't match the one that is linked into
the u-boot env.
