This series reworks the coreboot firmware driver a bit to fix some bugs and then simplify the code by changing the design to get rid of the different platform drivers, remap memory with memremap() to fix sparse __iomem issue, and finally simplify code. There's some risk in changing to memremap() but I think that should work out alright. It will either return memory directly, or fallback to ioremap_cache() as has been done before.
Changes from v3: * Dropped last patch for resource reservation * Pick up review tags on patch#1 * Always unmap memory for table instead of keep it around Changes from v2: * A bunch more patches * Fix iounmap missing on error path * Fix bus getting unregistered on driver unbind and never registered again * Request exclusive access to table region * Pull out table signature check to driver probe Changes from v1: * Split out fixlet for DT based driver from platform driver change Cc: Wei-Ning Huang <[email protected]> Cc: Julius Werner <[email protected]> Cc: Brian Norris <[email protected]> Cc: Samuel Holland <[email protected]> Stephen Boyd (6): firmware: coreboot: Let OF core populate platform device firmware: coreboot: Unmap ioregion after device population firmware: coreboot: Make bus registration symmetric firmware: coreboot: Collapse platform drivers into bus core firmware: coreboot: Remap RAM with memremap() instead of ioremap() firmware: coreboot: Only populate devices in coreboot_table_init() drivers/firmware/google/Kconfig | 26 ++-- drivers/firmware/google/Makefile | 2 - drivers/firmware/google/coreboot_table-acpi.c | 88 ------------ drivers/firmware/google/coreboot_table-of.c | 82 ------------ drivers/firmware/google/coreboot_table.c | 126 ++++++++++++------ drivers/firmware/google/coreboot_table.h | 6 - 6 files changed, 98 insertions(+), 232 deletions(-) delete mode 100644 drivers/firmware/google/coreboot_table-acpi.c delete mode 100644 drivers/firmware/google/coreboot_table-of.c -- Sent by a computer through tubes
