LS2080ARDB current u-boot code is closely tied with qixis code at many places.
And if try to decouple QIXIS code with u-boot code, it will take a lot of code
changes.
So, I just bypassed the final QIXIS call keeping other code changes for Qixis
access via I2C.
For customized boards, which uses RDB code as reference, having proper way of
CPLD access via I2C will be useful.
Also the board issue of CPLD access via I2C is getting fixed in next similar
board LS2081ARDB.
Please suggest how to proceed on this.
You said the CPLD is not accessible via I2C bus. What do you get by
pretending it is there? You know once you define this macro and
CONFIG_QIXIS_I2C_ACCESS, all QIXIS access will go through I2C. If it
doesn't do what you expect, how good is that as a reference design?
One way to get around this hardware bug, is to handle NO_QIXIS.
