At least i.MX53 has errata ENGcm12360:
Occurs when a pending command which issues busy is completed.
For a command with R1b response, the proper software sequence
is to poll the DLA for R1b commands to determine busy
state completion. The DLA polling is not working properly for
the ESDHC module. This is relevant for all eSDHC ports (eSDHC1-4 ports)
DLA bit in PRSSTAT register cannot be
polled to wait for busy state completion.
Updated block guide to reflect that DLA is not applicable to detect
busy state, instead, should poll bit 24 in PRSSTAT register (DLSL[0] bit)
to check that wait busy state is over.

since the switch to common clock, ethernet driver doesn't works and
and access to the network leads to :
eth0: Read MDIO failed...
unable to handle NULL pointer dereference at address 0x000000c7
The problem is that bit 31 (SLEEP) of register HW_CLKCTRL_ENET is kept
to its default value (1) which means : "put Ethernet block in sleep mode.
CLK_H_MAC0(1), CLK_H_MAC0(1)_S, and CLK_ENET0(1)_TX are gated off.
Ethernet can be wakeup remotely in sleep mode"
In that case the FEC don't get its clock.
This patch fix the problem by toggling this bit when FEC's clock is
enabled.

This updates the NAND stuff to Linux-3.11-rc1. It is synchronized
as best as we can get:
- locks removed
- The splitting in different files we had to better support different
features has been dropped. Instead this is now done mostly with the
use of __maybe_unused
Some barebox adjustments are forward ported, like:
- Allow partial page writes
- Optionally allow to erase bad blocks
- check for all_ff before writing a page
