2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-02-07security/vboot: overwrite existing spaces during factory init for tpm2Andrey Pronin
In TPM 2.0 case, if the factory initialization is interrupted after defining, say, the kernel tpm nvram space but before writing to this space, the following will happen upon reboot when the factory initialization will be re-attempted. Writing to this space will be skipped, and coreboot will finish the factory initialization with this space remained unwritten. At a later stage, when the rollback logic will attempt to check the version in the kernel space, it will fail (TPM2.0 returns an error when reading from unwritten spaces), and the system will go into recovery with no way out (since the kernel space will never be written). This change fixes that by always writing to the kernel, MRC hash and firmware spaces during factory initialization, even if the space already existed by that time. BUG=b:71884828 TEST=delete, define, but not write to the kernel space; trigger factory initialization; coreboot should fill the kernel space and continue booting.
