2019-11-01lib/cbmem_top: Add a common cbmem_top implementationArthur Heymans
This adds a common cbmem_top implementation to all coreboot target. In romstage a static variable will be used to cache the result of cbmem_top_romstage. In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable needs to be populated by the stage entry with the value passed via the calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the same implementation as will be used as in romstage.

2019-01-24cbmem_top: Fix comment and remove upper limitPatrick Rudolph
There's no such limit on 64 Bit coreboot builds. * Fix comment in cbmem.h * Remove 4 GiB limit on Cavium SoCs Tested on opencellular/elgon. Still boots Linux as payload.

2018-08-10soc/cavium/cn81xx: Fix minor thingsPatrick Rudolph
* Move cbmem.c to cn81xx folder * Store CBMEM below 4 GiB * Make sure CBMEM doesn't overlap with ATF scratchpad * Fix ATF scratchpad not marked as reserved due to wrong calculation * The scratchpad is the last 1 MiB at the end of DRAM. Tested on Cavium CN81xx EVB: The ATF scratchpad is now marked reserved and the configuration tables are located below 4 GiB. Linux still boots.
