Hi all,
Finally I've got a bunch of SD cards to test eSDHC in various ways,
and more importantly now I have a lot of SDHS cards. ;-)
So, here are few fixes that make eSDHC work flawlessly on MPC83xx
SOCs with all SD and MMC cards that I have.
On MPC85xx (namely MPC8536 and MPC8569) SOCs there is one issue:
the cards can be detected and read just fine, but writing doesn't
work (no interrupts received). I'm currently investigating this.
Solved. It appears that eSDHC on MPC85xx has a normal write-protect
reporting. And eSDHC actually checks the WP pin, thus doesn't let
anybody to do any writes... I'll make some additional patches and
will send v2 soon.
