Use of scan_static_bus() and tree traversals is somewhat convoluted. Start cleaning this up by assigning each path type with separate static scan_bus() function. For ME, SMBus and LPC paths a bus cannot expose bridges, as those would add to the number of encountered PCI buses.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2015-04-22i2c/ww_ring: various driver fixes and improvementsVadim Bendebury
When in development environment, some SP5 devices might not have the LED ring attached. They are still fully functional, but when booting up are generating massive amount of i2c error messages. This patch prevents accesses to non-existing lp55321 devices. When loading the program into the device the vendor recommends 1 ms delay when accessing the program control register. This patch separates these accesses into a function and add a delay after every access. Another fix - advance the program address when loading multipage programs. Set the global variable register 3c, not used by coreboot programs, to a fixed value. This will allow depthcharge to avoid re-initializing the controller when not necessary.

2015-04-10TPM: Reduce buffer size to fix stack overflowJulius Werner
The TPM driver by default allocates a 4K transfer buffer on the stack, which leads to lots of fun on boards with 2K or 3K stack sizes. On RK3288 this ends up writing over random memory sections which dependent on the memlayout of the day might contain timestamp data (no big deal) or page tables (-> bad time). This patch fixes the problem by reducing the buffer size to slightly above 1K, which still seems to work as far as I can tell. There was already some really odd code that #undef'ed this value and redefined it with the lower number in one .c file (unfortunately not the one with the buffer declaration), with no explanation whatsoever...

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

I assume from the code in the TPM driver that the TPM spec defines different types of delays and timeouts which each have a particular duration, and that the TPM can tell you how long each type is if you ask it. There was a large table, some members of a data structure, and a function or two which managed the timeouts and figured their value for different operations. The timeout values for the various "ordinals" were never set in the vendor specific data structure, however, and always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d were never overridden from their defaults. This change gets rid of all the timeout management code and makes the "ordinal" timeout 2 minutes and the a, b, c, and d timeouts 2 seconds, the larger of the two default values.

One example are old Intel HT enabled CPUs which can't do microcode update in parallel.
