David Abdurachmanov	217d5e4880	generic: fu740: add workaround for CIP-1200 errata ... Instruction TLB can fail to respect a non-global SFENCE thus we need to flush the TLB using SFENCE.VMA x0, x0 See full description of CIP-1200 in Errata_FU740-C000_20210205 from https://www.sifive.com/boards/hifive-unmatched Signed-off-by: David Abdurachmanov <david.abdurachmanov@sifive.com> Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>	2021-07-27 15:29:59 +05:30

Anup Patel	f1aa9e54e0	platform: Add generic FDT based platform support ... We add generic FDT based platform support which provides platform specific functionality based on the FDT passed by previous booting stage. By default, the generic FDT platform makes following assumptions: 1. platform FW_TEXT_START is 0x80000000 2. platform features are default 3. platform stack size is default 4. platform has no quirks or work-arounds The above assumptions (except 1) can be overridden by adding special platform callbacks which will be called based on the FDT root node compatible string. By default, we compile OpenSBI generic platform as follows: $ make PLATFORM=generic For a non-standard FW_TEXT_START, we can compile OpenSBI generic platform as follows: $ make PLATFORM=generic FW_TEXT_START=<non_standard_text_start> Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>	2020-05-01 10:33:05 +05:30
