2015-06-09cbmem: add indicator to hooks if cbmem is being recoveredAaron Durbin
It can be helpful to certain users of the cbmem init hooks to know if recovery was done or not. Therefore, add this as a parameter to the hooks.

2015-05-26cbmem: remove cbmem_set_top()Aaron Durbin
Now that the users of cbmem_set_top() always provide a consistent cbmem_top() value there's no need to have cbmem_set_top() around. Therefore, delete it.

2015-05-26CBMEM: Fix S3 resume path without EARLY_CBMEM_INITKyösti Mälkki
Implementation for cbmem_find() did not work for boards without EARLY_CBMEM_INIT in romstage. This is required for S3 resume to work on AGESA plaforms. First broken with commit 0dff57d cbmem: switch over to imd-based cbmem Change-Id: I9c1a4f6839f5d90f825787baad2a3824a04b5bdc Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: http://review.coreboot.org/10299 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins)

2015-04-22cbmem: switch over to imd-based cbmemAaron Durbin
By design, the imd library still provdes dynamic growth so that feature is consistent. The imd-based cbmem packs small allocations into a larger entry using a tiered imd. The following examples show the reduced fragmentation and reduced memory usage. Before with dynamic cbmem: CBMEM ROOT 0. 023ff000 00001000 aaaabbbb 1. 023fe000 00001000 aaaabbbc 2. 023fd000 00001000 aaaabbbe 3. 023fc000 00001000 aaaacccc 4. 023fa000 00002000 aaaacccd 5. 023f9000 00001000 ROMSTAGE 6. 023f8000 00001000 CONSOLE 7. 023d8000 00020000 COREBOOT 8. 023d6000 00002000 After with tiered imd: IMD ROOT 0. 023ff000 00001000 IMD SMALL 1. 023fe000 00001000 aaaacccc 2. 023fc000 00001060 aaaacccd 3. 023fb000 000007cf CONSOLE 4. 023db000 00020000 COREBOOT 5. 023d9000 00002000 IMD small region: IMD ROOT 0. 023fec00 00000400 aaaabbbb 1. 023febe0 00000020 aaaabbbc 2. 023feba0 00000040 aaaabbbe 3. 023feb20 00000080 ROMSTAGE 4. 023feb00 00000004 Side note: this CL provides a basis for what hoops one needs to jump through when there are not writeable global variables on a particular platform in the early stages.
