Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410.
This adds support for S3C and S5P architectures (all of my knowledge) to the
serial driver. Since the only difference between them is in clock handling,
this is moved to an arch-dependent separate function.
Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.
This adds support for most

The mc13xxx driver correctly bails out on failure, but leaves
mc_dev initialized, so a later mc13xxx_get won't fail but returns
an invalid pointer. Fix this. While at it, remove some superfluous

The netX internal UART latches register settings and internally uses
them only if written in the correct order. Other orders may work, but
sometimes the UART gets stuck, as the baudrate has not correctly been

Backport 2 fixes back from Linux kernel (title verbatim from
Linux kernel log) :
- docg3 fix in-middle of blocks reads
- docg3 reduce read alignment burden
These 2 enable partial reads from the MTD (ie. read only the
111 first bytes), which enable linux kernel booting or UBIFS
from barebox.

As per MMC spec, once power has been applied to an SD card, the card
can take as much as 250ms to complete its power-up cycle, and become
responsive to CMD0.
When this delay was not in place, activating the SD card in the env
init failed sometimes. With it, no more failure are observed.

The pxamci driver was not waiting for the BUSY line to be
deasserted. This was specifically breaking the CMD12 at
the end of block multiple writes, when the SD card had not
time enough to commit the last write.
Fix it by waiting for PRG_DONE bit (which is actually the
busy signal end condition).

This is based on the following U-Boot commit:
commit 5f4b4f2fed3ab8590c8c06b78642f8c1467acacf

ehci: speed up initialization
According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

for chache handling the ehci driver iterates over the hardware lists
of QHs/TDs. As we have a fixed number of maximum entries in this lists
we can allocate them as arrays and and clean/invalidate the arrays
instead which is much simpler. While at it, move the allocation to
ehci_probe so that we do not lose memory each time ehci_init is called.
Also, use memalign to allocate the QHs/TDs.
