[U-Boot] [PATCH 0/7] Some patches for MPC8569E-MDS

[Anton Vorontsov]

Hello Kumar,

Just resending rebased MPC8569E-MDS patches with your comments
addressed, plus there some fixes in eSDHC patch for pilot boards
(BCSR registers changed).

Thanks,

[U-Boot] [PATCH 1/7] fdt_support: Add multi-serial support for stdout fixup

[Anton Vorontsov]

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

Jerry,

Can you review this & possibly ack.  I can take it via the 85xx tree  
to keep the rest of the patches in the sequence sane.

Yes, take it via the 85xx tree.  I've already acked it:

[U-Boot] [PATCH 2/7] mpc85xx: Add eSDHC support for MPC8569E-MDS boards

[Anton Vorontsov]

eSDHC is mutually exlusive with UART0 (in 4-bits mode) and I2C2
(in 1-bit mode). When eSDHC is used, we should switch u-boot console to
UART1, and make the proper device-tree fixups.

Because of an erratum in prototype boards it is impossible to use eSDHC
without disabling UART0 (which makes it quite easy to 'brick' the board
by simply issung 'setenv hwconfig esdhc', and not able to interact with
U-Boot anylonger).

So, but default we assume that the board is a prototype, which is a most
safe assumption. There is no way to determine board revision from a
register, so we use hwconfig.

[U-Boot] [PATCH 5/7] mpc85xx: Setup QE pinmux for SPI Flash on MPC8569E-MDS boards

[Anton Vorontsov]

SPI Flash (M25P40) is connected to the SPI1 bus, we need a few
qe_iop entries to actually enable SPI1 on these boards.

[U-Boot] [PATCH 6/7] mpc85xx: Configure QE UART for MPC8569E-MDS boards

[Anton Vorontsov]

To make QE UART usable by Linux we should setup pin multiplexing
and turn UCC2 Ethernet node into UCC2 QE UART node.

Also, QE UART is mutually exclusive with UART0, so we can't enable
it if eSDHC is in 4-bits mode on pilot boards, or if it's a prototype
board with eSDHC in 1- or 4-bits mode.
