Re: [U-Boot] [PATCH 07/10] sunxi: Fix end of kernel memory alignment for A33

2015-04-28 Thread Mark Rutland
Hi Hans, So it seems that I'm not the only one seeing this, and I've been wrongly blaming it on the A33, instead it seems to be a kernel bug, triggered on my A33 due to the display resolution it has. For details see: http://www.spinics.net/lists/arm-kernel/msg413811.html That's good

For unknown reasons the A33 needs the end of the memory we report to the kernel to be aligned to a multiple of 4 MiB. Without this things will hang when we hand over control to the kernel. Signed-off-by: Hans de Goede hdego...@redhat.com --- drivers/video/sunxi_display.c | 9 + 1 file
