[U-Boot] [GIT PULL] rpi: updates for v2019.10
by Matthias Brugger 09 Sep '19

09 Sep '19

Hi Tom, Please have a look on the following updates for Raspberry Pi. Especially we introduce basic RPi4 support \o/ I did some mistake while creating the tag, so I had to fix the rebase and overwrite the tag. That's why travis-ci [1] is not yet finished. Nevertheless travis-ci finished successfully with the old tag (same patches but different base) [2]. Regards, Matthias [1] https://travis-ci.org/mbgg/u-boot/builds/581754574 [2] https://travis-ci.org/mbgg/u-boot/builds/581603847 --- The following changes since commit d39221f33f0e78cc80d1304ab4ca4e4a3886fbff: Prepare v2019.10-rc3 (2019-08-26 20:16:42 -0400) are available in the Git repository at: https://github.com/mbgg/u-boot.git tags/rpi-next-2019.10 for you to fetch changes up to e0351b242a9bf60dd6abdfd44104bb702e7000a0: git-mailrc: Add rpi and bcm283x maintainer (2019-09-06 18:16:59 +0200) ---------------------------------------------------------------- - fix mailbox status register used for polling - fix bcm2835_sdhost to wait long enough for a transfer to complete - increase kernel image size from 8 MB to 64 MB on arm64 - add support for RPi4 - add prefixes for raspberry pi related stuff to git-mailrc ---------------------------------------------------------------- Andrei Gherzan (6): RPI: Add defconfigs for rpi4 (32/64) ARM: bcm283x: Define configs for RaspberryPi 4 RPI: Add entry for Raspberry Pi 4 model B ARM: bcm283x: Include definition for additional emmc clock RPI: Add memory map for bcm2711 git-mailrc: Add rpi and bcm283x maintainer Bonnans, Laurent (1): rpi: increase SYS_BOOTM_LEN to 64M on ARM64 Fabian Vogt (1): ARM: bcm283x mbox: Fix send status register Matthias Brugger (2): ARM: bcm283x: Add BCM283x_BASE define mmc: bcm283x: Add support for bcm2711 device in bcm2835_sdhci Raul Benet (1): mmc: bcm2835-host: Fix wait_transfer_complete arch/arm/mach-bcm283x/Kconfig | 67 ++++++++++++++++++++++++++++++ arch/arm/mach-bcm283x/include/mach/mbox.h | 14 +++---- arch/arm/mach-bcm283x/include/mach/sdhci.h | 6 +-- arch/arm/mach-bcm283x/include/mach/timer.h | 6 +-- arch/arm/mach-bcm283x/include/mach/wdog.h | 6 +-- arch/arm/mach-bcm283x/mbox.c | 6 +-- board/raspberrypi/rpi/rpi.c | 32 ++++++++++++-- configs/rpi_4_32b_defconfig | 33 +++++++++++++++ configs/rpi_4_defconfig | 33 +++++++++++++++ doc/git-mailrc | 4 ++ drivers/mmc/bcm2835_sdhci.c | 12 +++++- drivers/mmc/bcm2835_sdhost.c | 12 +++--- include/configs/rpi.h | 4 ++ 13 files changed, 200 insertions(+), 35 deletions(-) create mode 100644 configs/rpi_4_32b_defconfig create mode 100644 configs/rpi_4_defconfig

[U-Boot] [PATCH v2 0/4] NC-SI PHY Support
by Samuel Mendoza-Jonas 09 Sep '19

09 Sep '19

This series introduces support for the NC-SI protocol to u-boot, functionality which so far has only been available in vendor trees. NC-SI (Network Controller Sideband Interface) is a protocol to manage a sideband connection to a proper network interface, for example a BMC (Baseboard Management Controller) sharing the NIC of the host system. Probing and configuration occurs by communicating with the "remote" NIC via NC-SI control frames (Ethernet header 0x88f8). Since the RFC[0] the changes have been split out into a few different patches to make the overall changes more obvious. Additionally a few small improvements have been added including adding a check to see if NC-SI is already configured, and marking the PHY bus "reset" as invalid since it does not define a bus. An example of NC-SI setup before a normal network command: => dhcp net_loop: configuring NCSI first ethernet@1e660000: link up, 100 Mbps full-duplex mac:0c:c4:7a:d5:48:43 NCSI: probing channels NCSI: configuring channel 0 NCSI: configuration done!

[U-Boot] [PATCH] Revert "spi: Kconfig: Mark MXS_SPI has DEPRECATED"

[U-Boot] XHCI behavior
by Aaron Williams 07 Sep '19

07 Sep '19

Hi, I am seeing crashes in our XHCI implementation based on a Designware USB 3.1 core. One thing I noticed is that this core sets the PAE bit in the HCCparams. The result of this is that when there is a short packet and there are two TDs, then when PAE is set there will be two responses with the second one being success. I'm still not sure if the length field I'm seeing is correct or not, but it appears that neither Linux nor U-Boot can handle HCs with the PAE bit set. See the eXtendable Host Controller Interface 1.1 sections 4.10.1.1 and 5.3.6. With short packets with the PAE bit set with to TRBs I get two responses when the data fits in the first TRB. The first event TRB contains a short packet response with the length set to the amount of space within the first TRB that is actually used. The second TRB event is a success completion code, as is described in section 4.10.1.1.1. Personally I find this PAE bit a major pain in the arse that causes more trouble than it's worth. -Aaron -- Aaron Williams Senior Software Engineer Marvell Semiconductor, Inc.

[U-Boot] [PATCH 1/2] dm: spi: Return 0 if driver does not implement ops->cs_info
by Bin Meng 07 Sep '19

If an SPI controller driver does not implement ops->cs_info, that probably means any chip select number could be valid, hence let's return 0 for spi_cs_info().
