2007-09-14This is a full rewrite of all the CS5530/CS5530A code. The previous code wasUwe Hermann
mostly undocumented, had a broken coding style, contained lots of dead code and had several other problems, e.g. it enabled write access to the ROM (why?), it unconditionally enabled primary/secondary IDE (which should have a config option) and that even _twice_ (which is um... wrong). The new code - has 'ide0_enable' and 'ide1_enable' config options (which actually work) to enable/disable the primary/secondary IDE interface in Config.lb. - Does _not_ enable write access to the ROM (or is there some good reason to do that? If so, it should at least have a config option). - Contains a bit more documentation. - Uses readable (and documented) #defines instead of hardcoded magic values. - aaand... it actually compiles ;-) Yep, that's right. The previous code wouldn't even build, as it hadn't been fully ported from v1 (still used v1 functions which are simply not available in v2).

2007-06-02The UART disable code was causing a hang and was worked around with aMarc Jones
return that skipped the disable code. This patch removes the return and fixes the UART disable code. The problem was that the disable code was ORing bits into the Legacy_IO MSR causing issues with the LPC SIOs init code that would manifest as a hang because the IO would not be decoded correctly. ANDing to clear the bits fixes the issue. Signed-off-by: Marc Jones <marc.jones@amd.com> Acked-by: Ronald G.

2007-05-24Drop the src/southbridge/amd/cs5536_lx directory and its contents, asUwe Hermann
the new src/southbridge/amd/cs5536 code completely replaces it. The Artecgroup dbe61 board currently uses it, but that is broken anyway at the moment. A fix to use the new CS5536 code for it is being worked on.
