Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006110242000038] was created:

<snip>

General code modification for mpc7448hpc2 board support.

1. Add 7447A and 7448 processor support.
2. Add the following flags.

CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically (such as by switch on board), this flag should be set.

CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot relocates to RAM, this flag should be set

CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the system hang in exception, this flag should be set

There is a design issue for tsi108/109 pci configure read. When pci scan the slots, if there is no pci card, the tsi108/9 will cause a machine check exception for mpc7448 processor.
