CFG_CMD_LOADB loadb
CFG_CMD_LOADS loads
CFG_CMD_MEMORY md, mm, nm, mw, cp, cmp, crc, base,
- loop, mtest
+ loop, loopw, mtest
CFG_CMD_MISC Misc functions like sleep etc
CFG_CMD_MMC MMC memory mapped support
CFG_CMD_MII MII utility commands
and crc32 is the correct crc32 which the
area should have.
+- CONFIG_LOOPW
+ Add the "loopw" memory command. This only takes effect if
+ the memory commands are activated globally (CFG_CMD_MEM).
+
Building the Software:
======================
coninfo - print console devices and informations
ide - IDE sub-system
loop - infinite loop on address range
+loopw - infinite write loop on address range
mtest - simple RAM test
icache - enable or disable instruction cache
dcache - enable or disable data cache
