Patch merged into coreboot/master: southbridge/amd: add support for Bolton FCH
by gerrit＠coreboot.org 20 Nov '15

20 Nov '15

the following patch was just integrated into master: commit d2e8f6ad33c750853844c5674d1a1a926ad7d93a Author: Felix Held <felix-coreboot(a)felixheld.de> Date: Sun May 31 20:28:17 2015 +0200 southbridge/amd: add support for Bolton FCH The Bolton FCH needs different firmware files than the Hudson FCH. A small patch to vendorcode is probably needed to make the XHCI controller work. XHCI_DEVID in pci_devs.h is probably wrong for Hudson.

the following patch was just integrated into master: commit e536a4d91697fc49d865dfa5065d2cbb31cbc03f Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Sun Aug 2 21:31:17 2015 -0500 cpu/amd/fam10h-fam15h: Set northbridge throttle values The existing code did not set the northbridge throttle values on Family 15h, leading to sporadic and random deadlocks in the crossbar per AMD notes.

Patch set updated for coreboot: AMD/bettong: Add UART support

Zheng Bao (zheng.bao(a)amd.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11749 -gerrit commit 0b04b8b9bf08a3bd98c112c78f55d26f77556f9e Author: Zheng Bao <fishbaozi(a)gmail.com> Date: Fri Nov 20 22:48:34 2015 +0800 AMD/bettong: Add UART support The function delay in uart8250mem.c is not enough for hudson. I guess there are some problems in lapic_timer(). I uploaded a patch to gerrit to show the way to enable UART feature. http://review.coreboot.org/#/c/12343/4 Currently the HUDSON_UART is unchecked by default. Select HUDSON_UART to enable this feature. The UART is test at BIOS stage. Since it is not a standart UART device, the windows internal UART driver doesnt support it. I guess we need a driver to use it on windows.
