x86/boot: Fix memremap() related build failure

2017-07-20T09:37:58+00:00

The following commit: 5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data") causes new build failures on certain randconfigs: drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’: drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration] drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function) This is a case of parasitic header dependencies: the sfi_core.c file indirectly includes for typical - but not all configs. Including explicitly solves the build failure.

x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings

2017-07-18T09:37:58+00:00

The ioremap() function is intended for mapping MMIO. For RAM, the memremap() function should be used. Convert calls from ioremap() to memremap() when re-mapping RAM. This will be used later by SME to control how the encryption mask is applied to memory mappings, with certain memory locations being mapped decrypted vs encrypted.

SFI: use ioremap_cache() instead of ioremap()

2011-01-12T04:27:25+00:00

We copied ACPI's oversight of using ioremap() and creating non-cached table mappings when we should have been using ioremap_cache(). Signed-off-by: Len Brown

SFI: do not return freed pointer

2010-06-01T16:04:35+00:00

We never actually use the return value of sfi_sysfs_install_table() but it still seems wrong to return a freed pointer. Signed-off-by: Dan Carpenter Signed-off-by: Len Brown

SFI: add sysfs interface for SFI tables.

2010-05-27T16:46:20+00:00

Analogous to ACPI's /sys/firmware/acpi/tables/... create /sys/firmware/sfi/tables/ The tables are primariy for the kernel, but sometimes it is useful for user-space to be able to read them. Signed-off-by: Feng Tang Signed-off-by: Len Brown

SFI: add support for v0.81 spec

2010-05-25T15:41:43+00:00

There are 2 major changes from v0.81 to v0.7: 1. Consolidating the SPIB/I2CB tables into a new DEVS table, which is more expandable and can support other bus types than spi/i2c. 2. Creating a new GPIO table, which list all the GPIO pins used in the platform. However, to avoid breaking current platforms who use SFI v0.7 version firmware, the definitions for SPIB/I2CB will still be kept for a while Signed-off-by: Feng Tang Signed-off-by: Len Brown

SFI: remove __init from sfi_verify_table

2009-10-03T05:16:12+00:00

sfi_verify_table() is called at runtime, and thus cannot be __init Signed-off-by: Arjan van de Ven Signed-off-by: Len Brown

SFI: fix section mismatch warnings in sfi_core.c

2009-10-03T05:03:11+00:00

The function sfi_map_memory/sfi_unmap_memory uses early_ioremap/early_iounmap respectively, which refers to a __init function. And function sfi_check_table also refers to a __init function sfi_verify_table. Since the references are valid, so use __ref to get rid of the warnings. We were warned by the following warnings: LD vmlinux.o MODPOST vmlinux.o WARNING: vmlinux.o(.text+0xb6ba3a): Section mismatch in reference from the function sfi_map_memory() to the function .init.text:early_ioremap() The function sfi_map_memory() references the function __init early_ioremap(). This is often because sfi_map_memory lacks a __init annotation or the annotation of early_ioremap is wrong. WARNING: vmlinux.o(.text+0xb6bab6): Section mismatch in reference from the function sfi_unmap_memory() to the function .init.text:early_iounmap() The function sfi_unmap_memory() references the function __init early_iounmap(). This is often because sfi_unmap_memory lacks a __init annotation or the annotation of early_iounmap is wrong.
