Mathias Kresin 8fb714edd6 uboot-lantiq: danube: fix hanging lzma kernel uncompression At least since gcc 7.3.0 (OpenWrt 18.06) lwr/lwl are used in the assembly of LzmaProps_Decode. While the decission made by the compiler looks perfect fine, it triggers some obscure hang on lantiq danube-s v1.5 with MX29LV640EB NOR flash chips. Only if the offset 1 is used, the hang can be observed. Using any other offset works fine: lwl s0,0(a1) - s0 == 0x6d000080 lwl s0,1(a1) - hangs lwl s0,2(a1) - s0 == 0x0080xxxx lwl s0,3(a1) - s0 == 0x80xxxxxx It isn't clear whether it is a limitation of the flash chip, the EBU or something else. Force 8bit reads to prevent gcc optimizing the read with lwr/lwl instructions. Signed-off-by: Mathias Kresin <dev@kresin.me>		2021-11-14 21:36:15 +01:00
