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>
