Attached a patch that adds support for the 16-bit wide bus of System ACE
CF besides the existing support for the 8-bit wide bus.
The patch also sets the FORCECFGMODE bit in the control register when
the System ACE CF configuration controller is reset before reading a
sector. Without this bit set System ACE CF reconfigures an FPGA if the
CFGMODE pin is active whenever a sector is read.
The third hunk fixes a typo.

Good idea. I was doing this in board_early_init_f() but this seems like
a more logical place.

Attached a patch that adds support for the 16-bit wide bus of System ACE
CF besides the existing support for the 8-bit wide bus.
The patch also #ifdef's accesses to the System ACE CF configuration
controller. In combination with a Xilinx FPGA the reset sequence
resulted in the reconfiguration of the FPGA, an undesired result. The
patch excludes that reset sequence if U-Boot is run on an ML300 board.
The patch also fixes two typos.
