This series enables building various Versatile Express platform drivers as modules. The primary target is the Fast Model FVP which is supported in Android. As Android is moving towards their GKI, or generic kernel, the hardware support has to be in modules. Currently ARCH_VEXPRESS enables several built-in only drivers. Some of these are needed, but some are only needed for older 32-bit VExpress platforms and can just be disabled. -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAl68MeUQHHJvYmhAa2Vy bmVsLm9yZwAKCRD6+121jbxhw/96EACb8MVXgss/RBPfcfKeb46tgdP6XfxlDqma /lWdd88KM3YZI0ym8uBQZX/XwUmuU1bcbxv9E/j0i+i/YER7qrdbsYfeU5CLhAbA vidC1fRuqXNPZRsnc5PnVP913PvRiNgNfGM4BUxz5i7aLfl9IGcujdY/uekEoo2i 9nyAYxMmZBZsHU28y0nXuZaUK7mC7YDZFXM4z6u6Q0nnbS4r5C8b+cUCeTk0w8Ex pA1pTWjRFvnpT1wZZU65FRaxv33dO3MbReT84rbQvrRo/IDKFi+VfAw4/UJFWBoF Ck1cmEchjPcTf7ut/clET+LqCuCVESwmDGmOhJ78m7m8WxsdoaUSfJSsPNMF7dxE +ePIvl/jovqMnCCR+RKbpcIzQvOckk6zp1xnqQNDii46BSCayXQEYtoxRj0B0X3k c4izH58Z7NTUa+IbVf02bwqOl2qMlGSp2KocXNTrBqznRkmCiWB+HHmrX/TQusWL 22sDHuxGRjOhD2yINOMQGeol7fXmIH7M2rjjpoGR1cWGRT/Xj7xU3Eme/VAE0nQv VHFoWW6YDVAfsuwJePgPrHysZcH96mhTCRVo9Gx1xC0IaZpcxFPQkk0LTKtu5CWY jYA1ml1vLDCl7l/yzfQjdtSm6lLg15ihZ+M6jbPdPacdBqmBL5UmPf30sW53XXAG BagmwNHCNQ== =c5eS -----END PGP SIGNATURE----- Merge tag 'vexpress-modules-for-soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux into arm/soc VExpress modularization This series enables building various Versatile Express platform drivers as modules.

For this to work, either your bootloader needs to enable the CDMM

region at an unused physical address on the boot CPU, or else your

platform code needs to implement mips_cdmm_phys_base() (see
