The current 4-minute data transfer timeout is misleading and broken.
Instead of such a long wait, calculate the timeout duration based on
the length of the data transfer. The current formula is the transfer
length in bits, divided by a multiplication of bus frequency in Hz,
bus width, DDR mode and converted the mSec. The value is bounded from
the bottom to 10000 mSec.

In the eMMC spec, “Note that while the actual timing change is done,
the behavior of any command sent command sent (like CMD13) cannot be
guaranteed due to the asynchronous operation. Therefore it is not
recommended to use CMD13 to check the busy completion of the timing
change indication.” indicates that SEND_STATUS can not be send after
set-timing, so delete it.

We set the fifo_depth to 0x100 word in Rockchip platform, and
fifo_depth/2 must be multiple of dma_multiple_transaction_size.
So we can set DWMCI_MSIZE to 6 according to max
dma_multiple_transaction_size being 128.
The DWMCI_MSIZE must be set as larger as possible. If not, dma fifo will
be full, and crc error occur when the clock stop during the data phase.

BUG: If erase is set as MMC_ERASE_ARG, the erase command
perform an erase on erase group(s). If so, when the start
address is close to the next partition address and the
blkcnt is less than erase group size, the mmc_berase()
will recalculate the end address and may exceed the next
partition start address. This will erase the other partition
useful data.
Solve: Set erase mode as trim, the erase command perform an
erase on the sector(s).
The erase command of SD card perform an erase on the sector(s).
We can just send the start and end address to erase SD card
and send CMD38 with argument MMC_ERASE_ARG.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>
