Hey folks,
I'm attempting, again, to see what we need to do in order to use gcc- 8.x for U-Boot and ran into, again: https://patchwork.ozlabs.org/patch/920329/ which in short is that when using -mcpu=xscale gcc-8.x throws an odd error: cc1: error: switch -mcpu=xscale conflicts with -march=armv5te switch [-Werror]
Now note, U-Boot isn't passing -march= at all, just -mcpu=xscale which suggests perhaps something broke in upstream gcc. Looking at the kernel, it's not used -mcpu=xscale ever, just -mtune=xscale but that leads to different failures (seen here with gcc-7.3): CC drivers/usb/gadget/pxa25x_udc.o {standard input}: Assembler messages: {standard input}:779: Error: selected processor does not support `pld [lr]' in ARM mode {standard input}:1201: Error: selected processor does not support `pld [r7]' in ARM mode {standard input}:2519: Error: selected processor does not support `pld [r3]' in ARM mode {standard input}:2796: Error: selected processor does not support `pld [r3]' in ARM mode
So, what should we do about this? Is there still active interest in supporting the PXA platforms? Thanks folks!
We are actually still shipping Colibri PXA270 modules for another one or two years I believe after which Marvell stops selling us chips.
The strange thing is that I build U-Boot master more or less daily without any known issues currently using the regular gcc 8.2 2019.01 tool chain from ARM.
The only issue is the missing DM_MMC and/or DM_USB conversion which I started working on a long time ago but never came around properly debugging. I may pick that one up tomorrow again.
Cheers
