I have a problem with some changes you (Jeff) did in u-boot related to compact flash. Can you help me understand why you put this:
+ /* Reset the configruation controller */ + val = ace_readw(0x18); + val|=0x0080; + ace_writew(val, 0x18); +
into the systemace_read function? This is causing me grief, with the linux SystemACE indicating an error:
JTAG controller couldn't read configuration from the CompactFlash
while booting Linux with a ext3 partition on the SystemACE CF. When I comment those lines out of cmd_ace.c, my boot starts to work again.
I suspect this "reset" of the config portion of the systemace is causing the SystemACE to start trying again to configure when the reset is released at the end of a block read. I would so like to remove that little snippet of code, but if you had a positive reason why it should be there, we need to negotiate.
