Shaunak Saha 9a0c9ac912 soc/apollolake: Expose a function to read pmc bar
This patch exposes a function to read pmc bar.
PMC bar is read in function read_pmc_mmio_bar which
is defined static in file pmutil.c. This patch exposes
that functionality to call it from other files.

BUG=chrome-os-partner:53438
TEST= Read the PMC bar value properly from outside
      pmutil file.

Werner Zeh 61f4b42f2c fsp_broadwell_de: Enable Super I/O address range decode
If there is an external 16550 like UART, one needs to enable
the appropriate address ranges before console_init() is called
so that the init sequence can reach the external UART. Otherwise
the UART will only start working in ramstage and will produce
unreadable characters in romstage due to the lack of initialization.

Tested-on: Siemens MC_BDX1

Furquan Shaikh 165b6cf5c1 vbnv: Do not silently reset cache in read_vbnv
Currently, read_vbnv performs a reset of the vbnv cache if it is not
valid. However, this information is not passed up to the vboot layer,
thus resulting in missed write-back of vbnv cache to storage if vboot
does not update the cache itself.

Update read_vbnv to return a value depending upon whether it wants a
write-back to be performed when save is called.
Return value:
0 = No write-back required
1 = Write-back of VBNV cache is required.

We want to be able to easily change SDRAM clock rate for debugging
purposes. This patch adds configurations for 4 different clock rates.

Same configs are used for all rk3399 boards at 200, 666 and 800 MHz.
Kevin board does not run reliably at 666 MHz, an option for it is
added to run at 300 MHz, this option is available to Kevin only.

There is not much room left in the coreboot romstage section, this is
why the config file for 928 MHz is being added with this patch but is
not included in the code, one of the lower frequency options will have
to be dropped for the higher frequency option to be added.
