- Extend ub_dev_read() and ub_dev_recv() so they return the length actually
read, which allows for better control and error handling (this introduces
additional error code API_ESYSC returned by the glue mid-layer).

- Clean up definitions naming and usage.

- Other minor cosmetics.

Note these changes do not touch the API proper, so the interface between
U-Boot and standalone applications remains unchanged.

This uses the new MMC framework

Some contributions by Dave Liu <daveliu@freescale.com>

Signed-off-by: Andy Fleming <afleming@freescale.com>

Here's a new framework (based roughly off the linux one) for managing
MMC controllers.  It handles all of the standard SD/MMC transactions,
leaving the host drivers to implement only what is necessary to
deal with their specific hardware.

This also hooks the infrastructure into the PowerPC board code
(similar to how the ethernet infrastructure now hooks in)

Some of this code was contributed by Dave Liu <daveliu@freescale.com>

Signed-off-by: Andy Fleming <afleming@freescale.com>

The current MMC infrastructure relies on the existence of an
arch-specific header file.  This isn't necessary, and a couple
drivers were forced to implement dummy files to meet this requirement.
Instead, we move the stuff in those header files into a more appropriate
place, and eliminate the stubs and the #include of asm/arch/mmc.h

The ecm variable in sdram.c was being declared for all 8548, but only
used by specific 8548 boards, so we make that variable require those
specific boards, too

The nand code was using an index "i" into a table, and then re-using "i"
to set addresses for each upm.  However, then it relied on the old value
of i still being there to enable things.  Changed the second "i" to "j"

This patch makes accesses to the system memory cachable by removing the
caching-inhibited and guarded flags from the relevant TLB entries for
the TQM8548_BE and TQM8548_AG modules. FYI, the Freescale MPC85* boards
are configured similarly.

This results in a big averall performace improvement. TFTP downloads,
NAND Flash accesses, kernel boots, etc. are much faster.

As the reset vector is located at 0xfffffffc, all flash sectors from the
beginning of the U-Boot binary to 0xffffffff must be protected. On the
TQM8548-AG having small sectors at the end of the flash it happened that
the last two sector were not protected and an "erase all" left an
un-bootable system behind:

Update the 86xx reset sequence to try executing a board-specific reset
function.  If the board-specific reset is not implemented or does not

peripherals to be reset if needed.
