2019-01-13arch/x86: Drop Kconfig AP_SIPI_VECTORKyösti Mälkki
This was used to check romcc-built bootblock and romstage agree about the location of 16-bit entrypoint. There was no need to customize it as bootblock size requirement did not grow. Just check for a fixed location at 4 GiB - 4 KiB. With C_ENVIRONMENT_BOOTBLOCK we can have a proper symbol for the purpose, since it appears in the same compilation unit. It will adjust if C_ENV_BOOTBLOCK_SIZE changes.

2016-03-04arch/x86: rename reset_vector -> _startAaron Durbin
In order to align the entry points for the various stages on x86 to _start one needs to rename the reset_vector symbol. The section is the same; it's just a symbol change.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-08arch/x86/bootblock: Link in object files selected with bootblock-yAlexandru Gagniuc
As part of preparing for systems with non-memory-mapped media, we want to be able to call into C code. This change allows us to link C code directly into the bootblock. The steps of going from bootblock main() to CAR setup to C code will be implemented in subsequent patches. Note that a few files selected with bootblock-y will now be compiled for the bootblock as well, but since we enabled garbage collection, they will not be included in the final binary.

2015-10-07x86/bootblock: Use LDFLAGS_bootblock to enable garbage collectionAlexandru Gagniuc
The x86 bootblock linking is a mess. The bootblock is treated in a very special manner, and never received the update to link-time garbage collection. On newer x86 platforms, the boot media is no longer memory-mapped. That means we need to do a lot more setup in the bootblock. ROMCC is unsuitable for this task, and walkcbfs only works on memory-mapped CBFS. We need to revise the x86 bootflow for this new case. The approach this patch series takes is to perform CAR setup in the bootblock, and load the following stage (either romstage or verstage) from the boot media. This approach is not new, but has been done on our ARM ports for years. Since we will be adding .c files to the bootblock, it is prudent to use link-time garbage collection. This is also consistent to how we do things on other architectures. Unification FTW!

2015-07-13x86: flatten hierarchyStefan Reinauer
It never made sense to have bootblock_* in init, but pirq_routing.c in boot, and some ld scripts on the main level while others live in subdirectories. This patch flattens the directory hierarchy and makes x86 more similar to the other architectures.
