Mostly changes to the SRAM driver to allow for one SRAM region to be "claimed" by multiple changes. When a region is "claimed" it is removed or disconnected from the CPU's view. This is needed on the H6 and H616, which have one alias region seemingly shared between the video codec engine and the display engine. One minor fix for the RSB driver is also included. -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEE2nN1m/hhnkhOWjtHOJpUIZwPJDAFAmod2AsQHHdlbnNAa2Vy bmVsLm9yZwAKCRA4mlQhnA8kMCUND/4h+xocrSMz4T+gHAvffsGItDQrtyLreXem GNIdY7whCRo+6KgipnTgXtvqRCzBhiQx9PYM3BTLNLUCURdM0NAcooE/f1kidVOI BHOTvfX1cy9eoGVJpZnfMAdMT/MlIw6LC7C1n1y8H14q1ERWkAOeO+k1VE9lMbIj jI9YWCFPvq29F+gEZAlCZXZnMWkgrJiLixnVYyi32P1k/u3ykqoNx7TKHWPsWaj5 /lS22YJUkcf0ARAJhcTElxYLytuhUCE68KKYVD7cN8uojebbcTAJLSkO7INtEdD/ USkY5sdq1cmDQ42ejgSPkcaL3etwBAha1NceKFLEAYVto6GUziOmXaGw8TLJVMD7 8ILjzOVj28iUADqy43tvwkqzDNDgn1xy+wmZSiSb6b9N+htDNKHh37R8NeJd0EwY 8YC/r5H5JqwBFQ0PWXHnjeFNlp6lBZ3G/QWU9ztnsCaDKp8P4jtl8wCF843lACtj BKPFCQ/+dkAlxExClaUo1JewJqhjyghpLmoWRMy/azbkdx7B100hH3DabAicN7JH 1lJ+rvIgTmmlwmGYceQ6sdg//M1b+3emTQ2kX3cgPCra8srKnp5ZkJzwtK0J9OHv XEFzB9rtvBPYvKt0dk/eaQAKAZIq82j9vdrtMzI1A5LeUF3VMEr7BxXxplBdwAH6 TSIElm0ktA== =n5X7 -----END PGP SIGNATURE----- Merge tag 'sunxi-drivers-for-7.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into soc/drivers Allwinner driver changes for 7.2 Mostly changes to the SRAM driver to allow for one SRAM region to be "claimed" by multiple changes.
