This patch adds a function getenv_bootm_mapsize() for obtaining the size of the early mapped region accessible by the kernel during early boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined, defaults to getenv_bootm_size(), which in turn defaults to the size of RAM.
getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize" environmental variable.

getenv_bootm_base() doesn't exist in my tree, should it have been getenv_bootm_low()?

I don't have access to my 8360 board at the moment to execute test the code. :-/
