However with 4GB configs we need more MTRRs for the BIOS and so the WP MTRR needs to move.

2011-11-22Remove second-stage U-Boot from 2MB firmware imageSimon Glass
There is barely enough space for U-Boot in the 2MB SPI flash. We are moving to eMMC firmware anyway, so for now let's remove the second-stage U-Boot from the image. This only affects Seaboard, not Kaen.

2011-11-22UPSTREAM: Reduce build timesWolfgang Denk
U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.

2011-11-15arm: Tegra3: clear IO_RESET bit in pinmux registersTom Warren
Based on Tegra3 TRM, once E_18V bits in PMC are programmed, all IO_RESETs need to be cleared on LV blocks. If not, GPIO settings on related LV pins will always be set to low even if it is set to high. Specifically, it is observed that when IO_RESET bit is not cleared in VI_D4 pinmux register, the output of GPIO on VI_D4 (PL.02) is always low. That causes LVDS shutdown all the time. Also needed for SDMMC4 pins when booting from SPI.

2011-11-04Introduce ability to use hardware SPI mapping for read accesses.Vadim Bendebury
On X86 systems the hardware maps the bootprom SPI flash chip into the top of memory address range. This could be used for accessing all information in the SPI flash. The vboot-reference code requires access to FMAP sections containing cryptographic information, and as of today, u-boot reads the whole sections, which are 64 KB in size, even though the actual areas accessed by vboot-reference are much smaller. A much faster way of accessing this information would be just passing around pointers to the appropriate memory areas. This would eliminate one copy, and also would make sure that only the areas actually accessed get fetched from SPI flash. This patch provides this ability trying to keep code changes to a minimum. New feature is enabled by defining CONFIG_HARDWARE_MAPPED_SPI. The firmware storage API for file reads changes when the new configuration option is set: a pointer to pointer to buffer is passed to the read_spi() function instead of a pointer to buffer. When the new feature is enabled the read_spi() function sets the pointer value to point to the requested data instead of copying the data into the buffer. A new data type is introduced (read_buf_type), which is set to be a (void *) if the new feature is not enabled, or (void **) otherwise. This type is used as the buffer pointer in the spi_read() function. Code allocating/freeing buffers used to keep data read from SPI flash is now conditionally compiled. Call sites for the spi_read() function are modified to adjust the buffer pointer parameter (pass the address of the parameter instead of the parameter, when the new feature is enabled). gbb field access functions can be aliased to gbb_init(), as they all in fact do the same - read a certain section of the gbb area. This change does not benefit the ARM implementations, and makes the code more complicated that it should be. Some u-boot rearchitecture along with vboot_reference API enhancements could address this. A tracking issue (http://code.google.com/p/chromium-os/issues/detail?id=22528) has been opened for that. BUG=chrome-os-partner:6585, chromium-os:22528 TEST=manual . build a new stumpy firmware image . boot the stumpy, observe it start up chromeos. . assess the boot timing using the cbmem.py utility (this modification shaves in excess of 100ms off the boot time). . disable the new feature, build a stumpy image, observe that is still boots chromeOs. . run emerge-terga2_kaen chromeos-u-boot to confirem that ARM version builds cleanly.
