Memory split 2G/2G is enabled as needed for SPEAr1310 RevC board to boot.
Before enabling this option the boot was hanging at uncompressing linux.

Hi Vijay,
By mistake you have added an ST internal list in cc, fixed it now.
Subject should be:

Unrelated chages. Don't get them in next time. In case they
just got added automatically because you did and make savedefconfig,
do a make savedefconfig before any of these patches to make things
stable for all SPEAr SoCs. And then add these patches.

I disagree. The subject could have been "put our head in the sand and
paper over bugs".
Please don't do that. There is no reason for any machine not to boot
way past "Uncompressing Linux" with the default split. The likely
reason it works with the 2G:2G split is because in that case the virtual
and physical RAM addresses in the kernel are the same, and therefore
missing p2v or v2p conversions are invisible.

I agree. Actually the details are misleading. SPEAr13xx chose this
option just for its own preference over high memory support.
@Vijay,
I think you should drop this patch and just enable high memory support
rather, if SPEAr13xx doesn't have any problem with that.

This patch is to correct clcd pin group name "clcd_high_res" to
"clcd_high_res_grp" to avoid kernel boot hang as with following error message.
spear1310-pinmux e0700000.pinmux: invalid group "clcd_high_res" for function
"clcd".

Remove "the" from subject.

Write it as:
Incorrect pin group name "clcd_high_res" is passed from DT, which causes boot
failure. Fix it by replacing it with "clcd_high_res_grp".

This Patch is to enable CONFIG_AEABI option in kernel. Which basically adds
support for latest ARMABI (EABI).
It also include support for changes the kernel syscall calling convention to
disambiguate both ABIs and allow for backward compatibility support.
Without this option the kernel crashes. Crash log is below:
