Subject: [PATCH v2 0/6] ARM64: meson: GXBaby (S905) and Vega S95 enablement
Date: Wed,  2 Mar 2016 03:34:55 +0100	[thread overview]
Message-ID: <1456886101-22967-1-git-send-email-afaerber@suse.de> (raw)

Hello,

This series adds initial support for the Amlogic S905 based
Tronsmart Vega S95 Pro, Meta and Telos TV boxes.

v2:
* Pick up previously acked "tronsmart" patch instead (Matthias)
* Drop ARM_GIC selection (Sudeep)
* Change some compatible strings (Sudeep, André)
* Squash some node changes/additions

Note: On the Vega S95 I need to change TEXT_OFFSET as follows,
in order to avoid the vendor U-Boot overwriting itself (fwiu);
for the Mini Mx that's reportedly not necessary.

+TEXT_OFFSET := 0x01080000
 endif
 
 # KASAN_SHADOW_OFFSET = VA_START + (1 << (VA_BITS - 3)) - (1 << 61)

This in turn runs into an apparent regression introduced with the
text offset randomization:
