Currently the version defines reflect the digits in the version

is defined as 0x405. This results in MMC_VERSION_4_5 < MMC_VERSION_4_41

Linux specifies the linux,stdout-path property in the /chosen node
in the devicetree. Unfortunately this is ignored in most cases.
For cases in which barebox uses this property for its own use we
translate this into a Linux boot arg with:
- the console name provided by the serial driver
- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.
So with this it's for devicetee enabled boards no longer necessary
to manually assign a console= parameter. Should a user not want
to use the automatically assigned parameter it should do:
global.linux.bootargs.console=

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.

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
