Would there be interest in a patch to provide rudimentary IGMP

This patch adds support for 16 bit NAND devices attached to the

This patch series mainly updates digsy_mtc board to initialize
graphic extention hardware and add splash screen support.
The last patch is an update for mtc appreg command.

Add detection of Coral-PA and configure Coral CCF an MMR parameters

Use CCF and MMR parameters for Coral-P Eval. Board if the appropriate
macros weren't defined.

PCI cards might need some time after reset to respond.
On some boards (mpc5200 or mpc8260 based) the PCI bus reset is
deasserted at pci_board_init() time, so we can not use available
pcidelay option for waiting before pci bus scan here. Add an option
to delay bus scan by setting pci_scan_delay
A delay of approximately 250 ms after PCI bus reset in
pci_mpc5xxx_init() is needed to recognize the Coral-PA
controller on graphic extention board. With this option
enabled we can set the environment variable pci_scan_delay
to the needed value.
