[PATCH] ARM: 2686/2: AAEC-2000 Core support Patch from Bellido Nicolas Core support for AAEC-2000 based platforms. This is an updated version of the previous patch, and takes into account Russell's comments. AAED-2000 default configuration will follow as soon as some problems with the bootloader are sorted out...

[ARM] Fix decompressor serial IO to give CRLF not LFCR As per the corresponding change to the serial drivers, arrange for ARM decompressors to give CRLF. Move the common putstr code into misc.c such that machines only need to supply "putc" and "flush" functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
