Julius Werner d2777b8485 Revert "cbfs: Skip mcache in post-RAM stages before CBMEM is online"
This reverts commit b652aaef99. It was
dumb and didn't actually fix anything.

Raul E Rangel f56b784227 soc/amd/picasso: Rename SD_EMMC_EMMC_DDR_52 to SD_EMMC_EMMC_DDR_104
The number at the end actually means the max MiB/s. So 52 MHz clock @ 8x
data width, sampled on each clock edge = 104 MiB/s.

According to JEDEC Standard No. 84-B51A (JESD84-B51A), maximum bandwidth
& clock frequency for various MMC bus speed modes are (at x8 bus width):
MMC_Legacy: 26 MB/s at 26 MHz Single Data Rate (SDR)
MMC_HS: 52 MB/s at 52 MHz SDR
MMC_DDR52: 104 MB/s at 52 MHz Dual Data Rate (DDR)
MMC_HS200: 200 MB/s at 200 MHz SDR
MMC_HS400: 400 MB/s at 200 MHz DDR

Furquan Shaikh 640f0ce93f mb/google/volteer: Reorganize FMAP
This change reorganizes FMAP for volteer to make use of the lower
16MiB of the SPI flash for RW_SECTION_A and RW_MISC in addition to
RW_LEGACY. This is now possible because TGL supports memory mapping of
BIOS region greater than 16MiB.

Following changes are made in chromeos.fmd as part of this:
1. Move RW_SECTION_A and RW_MISC to lower 16MiB.
2. Reduce size of RW_LEGACY to 2MiB since we longer need to use it as
a placeholder in the lower half of the SPI flash.
3. Reduce size of RW_ELOG to 4KiB as coreboot does not support a
larger region for ELOG.
4. Increase WP_RO to 8MiB to allow larger space for firmware
screens. GBB size is thus increased to 448KiB.

3. Add new helper function fast_spi_cache_ext_bios_postcar()

4. If the extended window is used, then it enables caching
for this window similar to how it is done for the standard

1. Make a call to fast_spi_enable_ext_bios() before the bus master
and memory space is enabled for the fast SPI controller.
2. Added a helper function fast_spi_enable_ext_bios() which calls
fast_spi_get_ext_bios_window() to get details about the extended
BIOS window from the boot media map.
3. Depending upon the SPI flash device used by the mainboard and
the size of the BIOS region in the flashmap, this function will
have to perform this additional configuration only if the BIOS
region is greater than 16MiB
4. Adddditionally, set up the general purpose memory range
registers in DMI.

Srinidhi N Kaushik 63afea54f4 soc/intel/common/dmi: Add DMI driver support
This change allows configuring the General Purpose
Memory Range(GPMR) register in BIOS to set up the decoding in DMI.

This driver provides the following functionality:
1. Add a helper function dmi_enable_gpmr which takes as input base,
limit and destination ID to configure in general purpose memory range
registers and then set the GPMR registers in the next available
free GMPR and enable the decoding.
2. Add helper function get_available_gpmr which returns available free
GPMR.
3. This helper function can be utilized by the fast SPI driver to
configure the window for the extended BIOS region.

Furquan Shaikh 493937e1d6 coreboot tables: Add SPI flash memory map windows to coreboot tables
This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.

`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

Furquan Shaikh 886f4e862a soc/intel/common/fast_spi: Add custom boot media device
This change enables support for a custom boot media device in fast SPI
controller driver if the platform supports additional decode window
for mapping BIOS regions greater than 16MiB. Following new Kconfigs
are added:
1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate
support for extended BIOS window.
2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the base address of the host space that is
reserved for mapping the extended window.
3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the size of the host space reserved for
mapping extended window.

If platform indicates support for extended BIOS decode window,
cbfstool add command is provided additional parameters for the decode
window using --ext-win-base and --ext-win-size.

It is the responsibility of the mainboard fmap author to ensure that
the sections in the BIOS region do not cross 16MiB boundary as the
host space windows are not contiguous. This change adds a build time
check to ensure no sections in FMAP cross the 16MiB boundary.

Even though the platform supports extended window, it depends upon the
size of BIOS region (which in turn depends on SPI flash size) whether
and how much of the additional window is utilized at runtime. This
change also provides helper functions for rest of the coreboot
components to query how much of the extended window is actually
utilized.

Julius Werner b652aaef99 cbfs: Skip mcache in post-RAM stages before CBMEM is online
There have been a few issues with the new CBFS mcache code in stages
after romstage, where the mcache resides in CBMEM. In a few special
cases the stage may be doing a CBFS lookup before calling
cbmem_initialize(). To avoid breaking those cases, this patch makes the
CBFS code fall back to a lookup from flash if CBMEM hasn't been
reinitialized yet in those stages.

Julius Werner 364f9de149 cbmem: Make cbmem_online() accurate on stages after romstage
cbmem_online() always returns 1 in stages after romstage. However, CBMEM
isn't actually immediately available in those stages -- instead, it will
only become available when cbmem_initialize() is called. That usually
happens very early in the stage, but there are still small amounts of
code running beforehand, so it is useful to reflect this distinction.
