* x86, intel-mid: Cleanup some platform code's header filesDavid Cohen2014-01-282-4/+5
| | | | | | | | | | | | | platform_ipc.h and platform_msic.h are wrongly declaring functions as external and with 'weak' attribute. This patch does a cleanup on those header files. It should have no functional change.

* x86: Don't add new __cpuinit users to Merrifield platform codePaul Gortmaker2014-01-222-2/+2
| | | | | | | | | | | | | | | | | | | Commit bc20aa48bbb3068224a1c91f8332971fdb689fad ("x86, intel-mid: Add Merrifield platform support") added new instances of __cpuinit usage. We removed this a couple versions ago; we now want to remove the compat no-op stubs. Introducing new users is not what we want to see at this point in time, as it will break once the stubs are gone. This also fixes an out of sync __init vs. __cpuinit -- as the former is real, and the latter is a no-op; hence it would have been a section mismatch. Cc: Fei Yang <fei.yang@intel.com> Cc: H.

* intel_mid: Move platform device setups to their own platform_<device>.* filesDavid Cohen2013-10-1724-429/+959
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Intel rolling out more SoC's after Moorestown, we need to re-structure the code in a way that is backward compatible and easy to expand. This patch implements a flexible way to support multiple boards and devices. This patch does not add any new functional support. It just refactors the existing code to increase the modularity and decrease the code duplication for supporting multiple soc's and boards. Currently intel-mid.c has both board and soc related code in one file. This patch moves the board related code to new files and let linker script to create SFI devite table following this: 1. Move the SFI device specific code to arch/x86/platform/intel-mid/device-libs/platform_<device>.* A new device file is added for every supported device. This code will get conditionally compiled by using corresponding device driver CONFIG option. 2. Move the device_ids location to .x86_intel_mid_dev.init section by using new sfi_device() macro. This patch was based on previous code from Sathyanarayanan Kuppuswamy.

| | | | | | | | | | | | | | | | | | mrst is used as common name to represent all intel_mid type soc's. But moorsetwon is just one of the intel_mid soc. So renamed them to use intel_mid. This patch mainly renames the variables and related functions that uses *mrst* prefix with *intel_mid*. To ensure that there are no functional changes, I have compared the objdump of related files before and after rename and found the only difference is symbol and name changes.
