coreboot's build system picks up the BL31 image as an ELF from the ARM
Trusted Firmware submodule and inserts it into CBFS. However, the
generic 'bl31' build target we run in the ARM Trusted Firmware build
system also generates a raw bl31.bin binary file.
We don't need that binary, and with the recently added support for
multiple non-contiguous program segments in BL31 it can grow close to
4GB in size (by having one section mapped near the start and one near
the end of the address space). To avoid clogging up people's hard drives
with 4GB of zeroes, let's only build the target we actually need.

The Kevin project has been too smooth and boring for our tastes in the
last last few weeks, so we've decided to stir the pot a little bit and
reshuffle all our PLL settings at the last minute. The new settings
match exactly what the Linux kernel expects on boot, so it doesn't need
to reinitialize anything and risk a glitch.
Naturally, changing PLL rates will affect child clocks, so this patch
changes vop_aclk (192MHz -> 200MHz, 400MHz in the kernel), pmu_pclk
(99MHz -> 96.57MHz) and i2c0_src (198MHz -> 338MHz, leading to an
effective I2C0 change 399193Hz -> 398584Hz).

Currently the code considers the absence of the NVRAM firmware
rollback space a a trigger for invoking the TPM factory initialization
sequence.
Note that the kernel rollback and MRC cache hash spaces are created
after the firmware rollback space. This opens an ever so narrow window
of opportunity for bricking the device, in case a startup is
interrupted after firmware space has been created, but before kernel

The suggested solution is to create the firmware space last, and to
allow for kernel and MRC cache spaces to exist during TPM factory
initialization.

The TPM spaces created by the RO need to have different attributes
depending on the space's use. The firmware rollback counter and MRC
hash spaces are created by the RO code and need to be protected at the
highest level: it should be impossible to delete or modify the space
once the RO exits, and it is how it is done before this patch.
The rest of the spaces should be possible to modify or recreate even
after the RO exits. Let's use different set of NVRAM space attributes
to achieve that, and set the 'pcr0 unchanged' policy only for the
firmware counter and MRC cache spaces.
The definitions of the attributes can be found in "Trusted Platform

This variable can be set in a debugger (e.g. Spike)
to finely control which traps go to coreboot and
which go to the supervisor.

to kernels and hypervisors. Change the payload function to pass
this string in a0.

These functions will allow us to remove hardcodes,
as long as we can verify the qemu and lowrisc targets
implement the configstring correctly. Hence, for the
most part, we'll start with mainboard changes first.
Define a new config variable, CONFIG_RISCV_CONFIGSTRING,
which has a default value that works on all existing
systems but which can be changed
as needed for a new SOC or mainboard.
