From: Kumar Gala Date: Mon, 29 Nov 2010 20:32:11 +0000 (-0600) Subject: powerpc/85xx: Introduce CONFIG_SYS_EXTRA_ENV_RELOC X-Git-Tag: v2010.12-rc3~36 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a55bb8340ba8682782f816f0b9b3de13e5512e28;p=u-boot powerpc/85xx: Introduce CONFIG_SYS_EXTRA_ENV_RELOC Some systems need to relocate the env_addr pointer early because the location it points to will get invalidated before env_relocate is called. One example is on systems that might use a L2 or L3 cache in SRAM mode and initialize that cache from SRAM mode back to being a cache in cpu_init_r. We set this on the 85xx boards that have support for NAND, SPI, or SDHC/MMC boot support as they use a secondary cache in SRAM mode and need the env_addr pointer relocated since we change from SRAM to normal cache mode in cpu_init_r. Also removed CONFIG_SYS_SPL as its not used anywhere.
