[U-Boot] [PATCH v1] Refactor linker-generated arrays

[Daniel Schwierzeck]

Hi Albert,

2013/2/2 Albert ARIBAUD <albert.u.boot at aribaud.net>:
> 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.

for the MIPS part:

BTW: if we use

	.u_boot_list : {
		KEEP(*(SORT(.u_boot_list*)))
	}

we can get rid of the undef magic in the final link of u-boot
