2010-06-01SFI: do not return freed pointerDan Carpenter
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 <error27@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-05-27SFI: add sysfs interface for SFI tables.Feng Tang
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 <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-05-25SFI: add support for v0.81 specFeng Tang
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 <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-10-03SFI: remove __init from sfi_verify_tableArjan van de Ven
sfi_verify_table() is called at runtime, and thus cannot be __init Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-10-03SFI: fix section mismatch warnings in sfi_core.cRakib Mullick
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. WARNING: vmlinux.o(.text+0xb6be30): Section mismatch in reference from the function sfi_check_table() to the function .init.text:sfi_verify_table() The function sfi_check_table() references the function __init sfi_verify_table(). This is often because sfi_check_table lacks a __init annotation or the annotation of sfi_verify_table is wrong.

2009-08-28SFI: add platform-independent core supportFeng Tang
drivers/sfi/sfi_core.c contains the generic SFI implementation. It has a private header, sfi_core.h, for its own use and the private use of future files in drivers/sfi/ Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
