* layout: Tidy up forward declarationsNico Huber2021-06-261-7/+7
| | | | | | | | | | | | | | | | * Parameter names like `flashctx` for a `struct flashrom_flashctx` don't add any value. * `const` qualification of parameters is meaningless in forward declarations. Arguments are always passed by copy and an API user does not need to know what callees do with their copy.

We replace the two special cases `single_layout` and `ich_layout` with dynamically allocated layouts.

* layout: Increase max rom layout sizePatrick Rudolph2019-07-041-1/+1
| | | | | | | | | | | | | | | | | | When trying to flash a single FMAP region on VBOOT enabled boards the default of 32 entries is to small to store all regions. Flashrom will bail out with "Cannot add fmap entries to layout - Too many entries." Increase the maximum rom layout size to 128 to support complex FMAPs. Tested on coreboot's UP/squared mainboard using SF600. With this patch it's possible to update a single FMAP region.
