The first patch fixes SH4 compiler flag fallback handling for toolchains which support SH4A targets but do not provide the plain -m4-nofpu option. The second patch adds the SH7305 CPU subtype, processor name and CPU probe. This is the first small architecture level part of ongoing SH7305 enablement. Platform specific clock, interrupt controller, timer and board support are intentionally left for separate patches. The SH7305 support has been compile tested with GCC 14.3.0 targeting big endian SH4A. Changes in v2: - Use my full name, Artem Novak, for authorship and Signed-off-by. - No code changes.
