2014-08-13arm: libpayload: Add cache coherent DMA memory definition and managementJulius Werner
This patch adds a mechanism to set aside a region of cache-coherent (i.e. usually uncached) virtual memory, which can be used to communicate with DMA devices without automatic cache snooping (common on ARM) without the need of explicit flush/invalidation instructions in the driver code. This works by setting aside said region in the (board-specific) page table setup, as exemplary done in this patch for the Snow and Pit boards. It uses a new mechanism for adding board-specific Coreboot table entries to describe this region in an entry with the LB_DMA tag. Libpayload's memory allocator is enhanced to be able to operate on distinct types/regions of memory. It provides dma_malloc() and dma_memalign() functions for use in drivers, which by default just operate on the same heap as their traditional counterparts. However, if the Coreboot table parsing code finds a CB_DMA section, further requests through the dma_xxx() functions will return memory from the region described therein instead.

There are three coreboot table tags that all define some kind of memory region, and each has their own homologous struct. I'm about to add a fourth so I'll just clean this up and turn it into a generic struct lb_range instead.

2013-04-20Eliminate use of pointers in coreboot tableStefan Reinauer
Because pointers can be 32bit or 64bit big, using them in the coreboot table requires the OS and the firmware to operate in the same mode which is not always the case. Hence, use 64bit for all pointers stored in the coreboot table. Guess we'll have to fix this up once we port to the first 128bit machines.

An example usage implementation would be to obtain the variable MTRR index that covers the ROM from the coreboot tables. Then one would disable caching and change the MTRR type from uncacheable to write-protect and enable caching. The opposite sequence is required to tearn down the caching.

Some bootloaders seem to overwrite memory starting at 0x600, thus destroying the coreboot table integrity, rendering the table useless. By moving the table to the high tables area (if it's activated), this problem is fixed. In order to move the table, a 40 bytes mini coreboot table with a single sub table is placed at 0x500/0x530 that points to the real coreboot table. This is comparable to the ACPI RSDT or the MP floating table. This patch also adds "table forward" support to flashrom and nvramtool.
