Replace ARCH_BCM4908 with ARCH_BCMBCA in subsystem Kconfig files.
This change will make symbols (and relevant drivers):
1. MTD_OF_PARTS_BCM4908
2. MTD_OF_PARTS_LINKSYS_NS
3. BCM4908_ENET
4. PINCTRL_BCM4908
available on all BCA (sub)families.
Above drivers are BCM4908 specific and I think they will never be needed
for other BCA (sub)families. That list seems to be growing big:
BCM47622, BCM4912 BCM63138, BCM63146, BCM63148, BCM63158, BCM63178,
BCM6756, BCM6813, BCM6846, BCM6855, BCM6856, BCM6858, BCM6878.
So I'm still wondering if dropping ARCH_BCM4908 makes sense. It seems to
me we're saving 10 lines of clean Kconfig code while introducing a bit
of mess to kernel config.
If you take a look at Documentation/kbuild/kconfig-language.rst it says
that symbols visibility should be limited to platform(s) (check the
"Architecture and platform dependencies" part). There is there is
however no clear documentation what platform should be.
Personally I think I'd:
1. Keep ARCH_BCM4908 for BCM4908 (BCM4906 too) specific stuff
2. Use ARCH_BCMBCA for actual BCA-generic drivers (serial, WD, PMB)
I'm happy to hear other maintainers opinions.
