Hi All,<br><br>I am working on a port of u-boot to a PPC440EPx custom board based off of the Sequoia reference design.<br><br>I have noticed a couple of areas that the stock sequoia u-boot sources configure the EBC0 & EBC3 with reserved bits, namely the B0CR with 0xDA000, where bits 19:31 are reserved & B0AP with 0x03017200, where bits 9:11 are reserved.
<br><br>I have searched for an ERRATA in the datasheets but do not see anything with reference to the EBC peripheral bus.<br><br>Can anyone explain why these bits are set? or has the info for their usage?<br><br>Thanks<br>
Frank<br>
