Build mali on sunxi-next

[avafinger]

Hi @mripard

I have tried to compile r6p2 on 5.5.0-rc5-next-20200109+ , but got this

sunxi-mali/r6p2/src/devicedrv/mali/linux/mali_osk_low_level_mem.c: In function ‘_mali_osk_mem_mapioregion’:
/arm/ubuntu/nanopi-a64-linux-next/sunxi-mali/r6p2/src/devicedrv/mali/linux/mali_osk_low_level_mem.c:36:26: error: implicit declaration of function ‘ioremap_nocache’; did you mean ‘ioremap_cache’? [-Werror=implicit-function-declaration]
  return (mali_io_address)ioremap_nocache(phys, size);
                          ^~~~~~~~~~~~~~~
                          ioremap_cache

  return (mali_io_address)ioremap_nocache(phys, size);
         ^

There is no ioremap_nocache on linux-next, what would be the equivalent function? How would be the workaround?

Hi @avafinger,

I've tried to rebuild against torvalds/master branch and it has no problem at all. sunxi-next branch is not stable, it's only a branch where sunxi-specific patches are committed before being pulled from upstream(torvalds). So don't use sunxi-next branch, but at least a torvalds/master or a stable/version from greghk(better a tag).

Best regards

Yes, there you have ioremap_nocache. I thought linux-next would become the next rc. There i have codec analog fully working on my board.

Anyway, thanks for the info.
