From 0628ab8ec59834f98ede267edd21ddb8ba0bb57b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 24 Feb 2013 17:33:15 +0000 Subject: sandbox: Change memory commands to use map_physmem Sandbox wants to support commands which use memory. The map_sysmen() call provides this feature, so use this in the memory commands.

Add a new crc32_wd_buf() to make this possible, which puts its result in a buffer rather than returning it as a 32-bit value. Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features).
