2011-09-14	postload: Add new _reloc_end to define end of relocated area	Simon Glass
	Rather than __bss_end, define a new symbol which sets the end boundary of code to be relocated by relocate_code(). This allows us to add code after the BSS section which is still relocatable.

2011-08-29	tegra2: Run at slower speed until core voltage is ready	Simon Glass
	Previously we ran the T25 at 1.2GHz before increasing the voltage to the required level. This change starts up the PLLX at 1.0GHz and then increases it later after the i2c and pmc init.

2011-08-29	tegra2: Move cpu_init_crit() into CPU code file	Simon Glass
	This commits move this CPU code into the CPU code place where it is better suited. This also makes it happen slightly earlier in the boot. Mostly this code turns on the instruction cache.

2011-03-27	arm: fix incorrect monitor protection region in FLASH	Po-Yu Chuang
	Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead. Add _end to linker scripts for end of u-boot image Add _end_ofs to all the start.S. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
2010-10-29	Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC	Wolfgang Denk
	When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
2010-10-13	arm: implement ELF relocations	Albert Aribaud
	ELF relocation tables generated with linker option -pie can be used to fixup code and data in a single loop at relocation, removing the need for manual fixups anywhere else in the code. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>
2010-09-19	ARM: add relocation support	Heiko Schocher
	!! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.

2010-04-13	Move architecture-specific includes to arch/$ARCH/include/asm	Peter Tyser
	This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
