Various errata exist in the Cortex-A9 CPU, and may be worked around by
setting some bits in a CP15 diagnostic register. Add code to implement
the workarounds, enabled by new CONFIG_ options.This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S,
and modified to remove the logic to conditionally apply the WAR (since we
know exactly which CPU we're running on given the U-Boot configuration),
and use r0 instead of r10 for consistency with the rest of U-Boot's
cpu_init_cp15().Signed-off-by: Stephen Warren

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.Conflicts:

Turn __bss_start and __bss_end__ from linker-generated
to compiler-generated symbols, causing relocations for
these symbols to change type, from R_ARM_ABS32 to
R_ARM_RELATIVE.This should have no functional impact, as it affects
references to __bss_start and __bss_end__ only before
relocation, and no such references are done.Signed-off-by: Albert ARIBAUD

Many SPL linker scripts needlessly include linker lists (aka LGAs).
Remove them whenever possible; keep it only in the seven am335x_evm
variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot),
where there is actual content in output section .u_boot_list.This commit keeps all u-boot.bin and u-boot-spl.bin in ARM targets
byte-identical.Signed-off-by: Albert ARIBAUD

Output section .u_boot_list was left unmapped in
u-boot-spl.lds for omap-common, causing the location
counter to roll back to bteween .rodata and .data,
making __image_copy_end and _end symbols wrong.Mapping output section .u_boot_list to memory .sram
fixes these symbols' mapping.This modifies the SPL binary but has no functional
impact, as __image_copy_end and _end are never used
in SPLs and u_boot_list is empty for all 29 boards
