[U-Boot] [PATCH v2 0/9] x86: fsp: Move platform-specific config to chipset directory

[U-Boot] [PATCH v2 0/9] x86: fsp: Move platform-specific config to chipset directory

[Bin Meng]

All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf
as defined by the 1.0 spec, however there are FSPs that do not
follow 1.0 spec, like Intel FSP for 3rd generation Intel Core and
Intel Celeron processors with mobile Intel HM76 and QM77 chipsets
platform (formerly Chief River Platform: Ivy Bridge and Panther
Point). Although Intel website says this FSP conforms to FSP v1.0
specification which defines the UPD usage, it is not really the case.
This might possible due to that FSP predates the 1.0 spec. Also
future FSP binary that is complaint to v1.1 spec defines an optional
paltform-specific runtime data in the struct fspinit_rtbuf.

Besides this fspinit_rtbuf, the IvyBridge FSP does not support UPD
either, so that current codes in arch/x86/lib/fsp/fsp_support.c
won't work for that FSP. We need some flexibility, hence move those
platform-specific config to chipset directory.

Right now we still use hardcoded 'const struct' table (in flash)
to pass the Azalia (Intel HD Audio) verb table to FSP, because
different FSP may use different verb table format (at least for
Queensbay and BayTrail), we cannot handle this in the common FSP
support codes. But with this series, we are now able to get Azalia
verb table from device tree, just like what we did for overriding
UPD data configuration. This can be done in future patch set.

Changes in v2:
- Include a common struct fsp_cfg_common in the struct fsp_config_data.
- New patch to introduce CONFIG_FSP_USE_UPD Kconfig option
- split this patch from v1 patch#7

[U-Boot] [PATCH v2 1/9] x86: fsp: Simplify fsp_continue()

[Bin Meng]

There is no need to pass shared_data to fsp_continue() so we can
remove unnecessary codes that simplifies the function a lot.

[U-Boot] [PATCH v2 4/9] x86: fsp: Rename shared_data to fsp_config_data

[Bin Meng]

FSP has several config data like UPD, HDA verb table which can be
overridden or provided by bootloader. Currently in U-Boot only UPD
is handled via struct shared_data. To accommodate any platform, we
rename shared_data to fsp_config_data and move the definition from
common place fsp_support.h to platform-specific place fsp_configs.h.

[U-Boot] [PATCH v2 6/9] x86: fsp: Introduce CONFIG_FSP_USE_UPD Kconfig option

[Bin Meng]

Not every FSP supports UPD, thus we introduce a Kconfig option
CONFIG_FSP_USE_UPD and use it to wrap these common UPD handling
codes in fsp_support.c.

[U-Boot] [PATCH v2 8/9] x86: fsp: Move struct fspinit_rtbuf definition to chipset header

[Bin Meng]

All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf
as defined by the 1.0 spec, however there are FSPs that does not
follow 1.0 spec (possible due to that FSP predates the 1.0 spec),
and future FSP binary that is complaint to v1.1 spec defines an
optional paltform-specific runtime data in the struct fspinit_rtbuf.
Hence move the definition to chipset header.
