2018-05-04 | lib/bootmem: Add method to walk memory tables | Patrick Rudolph | |
Add a method to walk bootmem memory tables and call a function for each memory range. The tables might not match with OS sight of view. Return true if the callback function returned false. Required for FIT support in coreboot to find a usable RAM region. Tested on Cavium SoC.

2018-05-04 | lib/bootmem: Add more bootmem tags | Patrick Rudolph | |
Introduce new bootmem tags to allow more fine grained control over buffer allocation on various platforms. The new tags are: BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that should not be touched by bootmem (by example: stack, TTB, program, ...). BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should not be touched by bootmem. Starting with this commit all bootmem methods will no longer see memory that is used by coreboot as usable RAM. Bootmem changes: * Introduce a weak function to add platform specific memranges. * Mark memory allocated by bootmem as BM_TAG_PAYLOAD. * Assert on failures. * Add _stack and _program as BM_MEM_RAMSTAGE. ARMv7 and ARMv8 specific changes: * Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE. ARMv7 specific changes: * Add _ttb_subtables as BM_MEM_RAMSTAGE.

2018-04-30 | lib/bootmem: Introduce custom bootmem tags | Patrick Rudolph | |
Introduce bootmem custom memory tags and use them instead of reusing LB_MEM tags. Use asserts in bootmem_add_range to verify parameters. Tested with uImage payload on Cavium SoC.

2018-04-16 | lib/bootmem: tightly couple bootmem_init to bootmem_write_memory_table | Aaron Durbin | |
In https://review.coreboot.org/25383 people were confused about the ordering of bootmem calls w.r.t. when entries are exposed to the OS. To alleviate this add a notion of bootmem being initialized. In addition to that, only mark bootmem initialized when bootmem_write_memory_table() is called. Any other calls to bootmem before that will report an error on the console.

2016-04-21 | lib/bootmem: allow architecture specific bootmem ranges | Aaron Durbin | |
A architecture-specific function, named bootmem_arch_add_ranges(), is added so that each architecture can add entries into the bootmem memory map. This allows for a common write_tables() implementation to avoid code duplication.

2015-10-31 | tree: drop last paragraph of GPL copyright header | Patrick 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.

2015-05-21 | Remove address from GPLv2 headers | Patrick 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> | |||
2014-03-03 | coreboot: introduce notion of bootmem for memory map at boot | Aaron Durbin | |
The write_coreboot_table() in coreboot_table.c was already using struct memrange for managing and building up the entries that eventually go into the lb_memory table. Abstract that concept out to a bootmem memory map. The bootmem concept can then be used as a basis for loading payloads, for example.
