2014-04-18console: Drop driver list in ramstageKyösti Mälkki
This framework was only available in ramstage. So we had to define console output functions separately for bootblock, romstage and SMM. Follow-up patches will re-enable all the consoles removed here, in a more flexible fashion, and with less lines-of-code and copy-paste. Also the driver list is not in a well-defined order and some of the loops could exit without visiting all drivers. NOTE: This build has no console in ramstage.

2014-03-20rmodules: use rmodtool to create rmodulesAaron Durbin
Start using the rmodtool for generating rmodules. rmodule_link() has been changed to create 2 rules: one for the passed in <name>, the other for creating <name>.rmod which is an ELF file in the format of an rmodule. Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

Boot speeds can be sped up by mirroring the payload into main memory before doing the actual loading. Systems that would benefit from this are typically Intel ones whose SPI are memory mapped. Without the SPI being cached all accesses to the payload in SPI while being loaded result in uncacheable accesses. Instead take advantage of the on-board SPI controller which has an internal cache and prefetcher by copying 64-byte cachelines using 32-bit word copies.

When building without option_table or when there is no entry for baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate. For OxPCIe use of 4 MHz for reference was arbitrary giving correct divisor for 115200 but somewhat inaccurate for lower baudrates. Actual hardware is 62500000 with 16 times oversampling.

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82, speedup by CACHE_ROM is reduced a lot. On the other hand this makes coreboot run out of MTRRs depending on system configuration, hence screwing up I/O access and cache coherency in worst cases. CACHE_ROM requires the user to sanity check their boot output because the feature is brittle. The working configuration is dependent on I/O hole size, ram size, and chipset. Because of this the current implementation can leave a system configured in an inconsistent state leading to unexpected results such as poor performance and/or inconsistent cache-coherency Remove this as a buggy feature until we figure out how to do it properly if necessary.

2014-02-06memranges: add memranges_update_tag() functionalityAaron Durbin
The memranges_update_tag() function replaces all instances that are tagged with old_tag and update to new_tag. This can be helpful in the MTRR code by adjusting the address space if certain memory types cause the MTRR usage to become too large.

2014-02-05load_payload: Use 32-bit accesses to speed up decompression.Vladimir Serbinenko
Flash prefers 32-bit sequential access. On some platforms ROM is not cached due to i.a. MTRR shortage. Moreover ROM caching is not currently enabled by default. With this patch payload decompression is sped up by theoretical factor of 4. Test on X201, with caching disabled: Before: 90:load payload 4,470,841 (24,505) 99:selfboot jump 6,073,812 (1,602,971) After: 90:load payload 4,530,979 (17,728) 99:selfboot jump 5,103,408 (572,429) Change-Id: Id17e61316dbbf73f4a837bf173f88bf26c01c62b Signed-off-by: Vladimir Serbinenko <phcoder@gmail.com> Reviewed-on: http://review.coreboot.org/5144 Reviewed-by: Aaron Durbin <adurbin@google.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins)

Haswell was the original chipset to store the cache in another area besides CBMEM. However, it was specific to the implementation. Instead, provide a generic way to obtain the location of the ramstage cache. This option is selected using the CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM Kconfig option.
