CFG_CMD_SETGETDCR Support for DCR Register access (4xx only)
CFG_CMD_SPI * SPI serial bus support

- CFG_INIT_RAM_ADDR:
"md/mw" commands.
Examples:
- => mdc.b 10 4 500
+ => mdc.b 10 4 500
This command will print 4 bytes (10,11,12,13) each 500 ms.
- => mwc.l 100 12345678 10

+ [ARM only] If these variables are defined, then

+ the memory controller) are omitted and/or U-Boot does
+ not relocate itself into RAM.
+ Normally these variables MUST NOT be defined. The
+ only exception is when U-Boot is loaded (to RAM) by
+ some other boot loader or by a debugger which
+ performs these intializations itself.

Implementation Internals:
CFG_INIT_RAM_ADDR should be somewhere that won't interfere
with your processor/board/system design. The default value
you will find in any recent u-boot distribution in
- Walnut405.h should work for you. I'd set it to a value larger
+ walnut.h should work for you. I'd set it to a value larger
than your SDRAM module. If you have a 64MB SDRAM module, set
it above 400_0000. Just make sure your board has no resources
that are supposed to respond to that address! That code in
establish some rules. Submissions which do not conform to these rules
may be rejected, even when they contain important and valuable stuff.
+Patches shall be sent to the u-boot-users mailing list.
When you send a patch, please include the following information with
it:
(using #ifdef), and the resulting code with the new feature
disabled must not need more memory than the old code without your
modification.
+
+* Remember that there is a size limit of 40 kB per message on the
+ u-boot-users mailing list. Compression may help.
