2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup. BRANCH=None BUG=None TEST=Built Jerry and Falco, booted Oak.

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.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2015-04-15Kconfig: Fix incorrect CONFIG_STACK_SIZE values for X86 and ARM64Julius Werner
Commit 54229a7 (arm: Fix checkstack() to use correct stack size) didn't quite hit the mark. Due to the crazy way our Kconfig includes work, It accidentally set CONFIG_STACK_SIZE to 0 even on architectures that need it. This patch fixes the issue by moving everything back to a single entry in src/Kconfig, making sure we end up with the intended numbers on all architectures. BRANCH=None BUG=chrome-os-partner:34750 TEST=Built for Pinky, Urara, Falco and Ryu. Confirmed that the generated .config contained CONFIG_STACK_SIZE=0x0 for the former two, and CONFIG_STACK_SIZE=0x1000 for the latter.

2015-04-14arm: Fix checkstack() to use correct stack sizeJulius Werner
checkstack() runs at the end of ramstage to warn about stack overflows, and it assumes that CONFIG_STACK_SIZE is always the size of the stack to check. This is only true for systems that bring up multiprocessing in ramstage and assign a separate stack for each core, like x86 and ARM64. Other architectures like ARM and MIPS (for now) don't touch secondary CPUs at all and currently don't look like they'll ever need to, so they generally stay on the same (SRAM-based) stack they have been on since their bootblock. This patch tries to model that difference by making these architectures explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to assume the whole (_estack - _stack) area in checkstack() instead. Also adds a BUG() to the stack overflow check, since that is currently just as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM HALTED" output) but a little more easy to spot. Such a serious failure should not drown out in all the normal random pieces of lower case boot spam (also, I was intending to eventually have a look at assert() and BUG() to hopefully make them a little more useful/noticeable if I ever find the time for it). BRANCH=None BUG=None TEST=Booted Pinky, noticed it no longer complains about stack overflows. Built Falco, Ryu and Urara.
