New subject: [U-Boot] [PATCH 2/2] armv8/ls1043aqds: use configuarable clock for non-QSPI boot

For QSPI boot and SD boot with QSPI, we could only read from FPGA through I2C to get the system clock and DDR clock info. However in U-Boot booting flow, I2C is not initialized when get_clocks() is called and thus it couldn't get correct value of the clocks. So the configuarable clock is only supported by non-QSPI boot.

Qianyu,

Please work with Yuan Yao on qixis access. We may have a solution to get the clocks on QSPI boot.

Yes. I have been discussing with Yuan Yao these days. Yesterday we tried to initialize i2c by writing several related registers and finally verified on LS2080AQDS board. Seems that this way is feasible and simple enough for us to read FPGA earlier. Then I’ll send a new version of this patch.

Regards, Qianyu
