[U-Boot-Users] XUPV2P support

Hi everbody,
diff file is in attachment.
Changes:
Support for XUPV2P board
BSP autoconfig support
Reset support - developments board without flash memory had problem
with reset command, because
after reset variable sbrk_base (in data segment) had the last value. I
removed the temporary code from env_common.c. I added code for clearing BSS
section and better control under MALLOC, MONITOR, GLOBAL_DATA and Stact
section. Please read the config files for ml401 and xupv2p boards.
And I have question about sysace.
I tried sysace driver for xilinx/ml300 on XUPV2P with PPC405, but my attempts
failed. Can somebody help me with sysace driver?
Best regards,
Michal Simek
