If the UART is used in DTE mode the RI and DCD bits in UCR3 become
irq enable bits. Both are set to enabled after reset and both likely
are pending.
Disable the bits also on UARTs not used in the boot loader to prevent
an interrupt storm when Linux enables the UART interrupts.

In case USB serial downloader has been used to load U-Boot start the

We have two commands to change the bootmode fuses:
mfgr_fuse which set fuse 0/5 and 0/6
and
updt_fuse which burns bit 4 of 0/5.
Before BSP 2.6 we fused in mfgr_fuse 0x5062, which boots
from the user partition of the eMMC.
To workaround certain hangs we moved to fastboot mode and
using the first bootpartition of the eMMC requiring a fuse
value of 0x5072 which could be achieved by the then added
updt_fuse command. At the same time the mfgr_fuse command
was changed to also fuse 0x5072, revert that second change
so that one can fuse both values, one with just mfgr_fuse
and the later with mfgr_fuse;updt_fuse.
Note that the mfgr_fuse command is only needed at module
production time, a customer might need to use updt_fuse
when upgrading an older module to be compatible with a
newer image. The command is integrated into the image
update scripts.

CC1 or CC2:
range | power supply | red led | console message
