RISC-V is moving towards OpenFirmware-derived device trees, and the old functions to read the config string don't work anymore.

There have been discussions about removing this since it does not seem to be used much and only creates troubles for boards without defaults, not to mention that it was configurable on many boards that do not even feature uart.

2016-10-24RISCV: Clean up the common architectural codeRonald G. Minnich
This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload, entering main() with no supporting assembly code for startup. The Harvey port is not complete so it just panics but ... it gets started. We provide a standard payload function that takes a pointer argument and makes the jump from machine to supervisor mode; the days of kernels running in machine mode are over. We do some small tweaks to the virtual memory code. We temporarily disable two functions that won't work on some targets as register numbers changed between 1.7 and 1.9. Once lowrisc catches up we'll reenable them. We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual memory setup code. We now use the _stack and _estack from memlayout so we know where things are. As time goes on maybe we can kill all the magic numbers.

Almost all boards and chipsets within the codebase assume or use SPI flash as the boot device. Therefore, provide an option for the boards/chipsets which don't currently support SPI flash as the boot device. The default is to assume SPI flash is the boot device unless otherwise instructed. This falls in line with the current assumptions, but it also allows one to differentiate a platform desiring SPI flash support while it not being the actual boot device. One thing to note is that while google/daisy does boot with SPI flash part no SPI API interfaces were ever implemented. Therefore, mark that board as not having a SPI boot device.

Since commit 3bfd7cc (drivers/pc80: Rework normal / fallback selector code) the reboot counter stored in `reboot_bits` isn't reset on a reboot with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR enabled, later stages (e.g. payload, OS) have to clear the counter too, when they want to switch to normal boot. So change the bits to (h)ex instead of (r)eserved. To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also remove all occurences of the obsolete `last_boot` bit that have sneaked in again since 24391321 (mainboard: Remove last_boot NVRAM option).

2016-07-12spike-riscv: Remove HTIF related codeJonathan Neuschäfer
The HTIF is deprecated and the newest RISC-V binutils don't know the mtohost/mfromhost CSRs anymore. The SBI implementation still needs to be restructured.

2016-06-21qemu/x86: car: drop pointless code, move stack out of the wayGerd Hoffmann
RAM doesn't need any initialization on qemu, so we can simply use it right away. No need to try using the cache as ram in the first place. We also can place the stack in normal ram right from start and we don't have to switch it to another place later on. Place the stack in real mode memory which isn't used for something else.

This is where the RAM is (now), on RISC-V. We need to put coreboot.rom in RAM because Spike (at the moment) only supports loading code into the RAM, not into the boot ROM.
