Ah-ha! Good catch. Note that on beagle/evm we do:
/*
* 1MB into the SDRAM to allow for SPL's bss at the beginning of SDRAM
* 64 bytes before this address should be set aside for u-boot.img's
* header. That is 0x800FFFC0--0x80100000 should not be used for any
* other needs.
*/
#define CONFIG_SYS_TEXT_BASE 0x80100000
#define CONFIG_SYS_SPL_MALLOC_START 0x80208000
#define CONFIG_SYS_SPL_MALLOC_SIZE 0x100000
So (a) I like the bigger comment and (b) I guess we don't need quite as
much space set aside?
