linux-toradex.git/arch/arm/include/debug/zynq.S, branch v4.9.51 Linux kernel for Apalis and Colibri modules ARM: zynq: Move early printk virtual address to vmalloc area 2016-02-25T13:06:03+00:00 Michal Simek michal.simek@xilinx.com 2016-02-15T09:17:47+00:00 8fff2f752f2c9d31414f83170157701b59aec4c1 The patch "ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000" (sha1: 6ff0966052c46efb53980b8a1add2e7b49c9f560) has moved also start of VMALLOC area because size didn't change. That's why origin location of vmalloc was vmalloc : 0xf0000000 - 0xff000000 ( 240 MB) and now is vmalloc : 0xf0800000 - 0xff800000 ( 240 MB) That's why uart virtual addresses need to be changed to reflect this new memory setup. Starting address should be vmalloc start address. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de> 
The patch
"ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000"
(sha1: 6ff0966052c46efb53980b8a1add2e7b49c9f560)
has moved also start of VMALLOC area because size didn't change.
That's why origin location of vmalloc was
   vmalloc : 0xf0000000 - 0xff000000   ( 240 MB)
and now is
   vmalloc : 0xf0800000 - 0xff800000   ( 240 MB)

That's why uart virtual addresses need to be changed to reflect this new
memory setup. Starting address should be vmalloc start address.
