bootstd: Support for distro specific EFI folders
by Shantur Rathore 10 Dec '23

10 Dec '23

Hi Simon, Currently bootstd - bootmethod_efi only looks for the default bootxx64.efi in /EFI/boot folder only. Generally many distros end up putting their bootloaders in EFI/<distro> folders like EFI/ubuntu and EFI/debian etc. In x86 worlds, the NVRAM is modified and new boot entries are added to support these but in the U-boot world the NVRAM variables are read-only. What would be the best way to implement this? I was thinking of having a "efi_prefixes" environment variable which can be set to "ubuntu debian centos" etc and bootmethod_efi can try all of them. Will bootmethod_efi be able to support multiple entries ( thinking of multiboot ) ? Regards, Shantur

[PATCH] mtd: nand: omap_gpmc: Fix NAND in SPL for AM335x
by Roger Quadros 09 Dec '23

09 Dec '23

AM335x uses a special driver "am335x_spl_bch.c" as SPL NAND loader. This driver expects 1 sector at a time ECC and doesn't work well with multi-sector ECC that was implemented in commit 04fcd2587321 ("mtd: rawnand: omap_gpmc: Fix BCH6/16 HW based correction") Switch back to 1 sector at a time read/ECC.

[PATCH] common: usb-hub: Reset hub port before scanning
by Shantur Rathore 09 Dec '23

09 Dec '23

Currently when a hub is turned on, all the ports are powered on. This works well for hubs which have individual power control. For the hubs without individual power control this has no effect. Mostly in these scenarios the hub port is powered before the USB controller is enabled, this can lead to some devices in unexpected state. With this patch, we explicitly reset the port while powering up hub This resets the port for hubs without port power control and has no effect on hubs with port power control as the port is still off. Before this patch AMicro AM8180 based NVME to USB adapter won't be detected as a USB3.0 Mass Storage device but with this it works as expected. Tested working after this patch: 1. AMicro AM8180 based NVME to USB Adapter 2. Kingston DataTraveler 3.0 3. GenesysLogic USB3.0 Hub The drives were tested while connected directly and via the hub. --- common/usb_hub.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/common/usb_hub.c b/common/usb_hub.c index 85c0822d8b..06fe436add 100644 --- a/common/usb_hub.c +++ b/common/usb_hub.c @@ -174,8 +174,10 @@ static void usb_hub_power_on(struct usb_hub_device *hub) debug("enabling power on all ports\n"); for (i = 0; i < dev->maxchild; i++) { + usb_set_port_feature(dev, i + 1, USB_PORT_FEAT_RESET); + debug("Reset : port %d returns %lX\n", i + 1, dev->status); usb_set_port_feature(dev, i + 1, USB_PORT_FEAT_POWER); - debug("port %d returns %lX\n", i + 1, dev->status); + debug("PowerOn : port %d returns %lX\n", i + 1, dev->status); } #ifdef CONFIG_SANDBOX -- 2.40.1

[PATCH v2 1/9] cmd: bdinfo: Optionally use getopt and implement bdinfo -a
by Marek Vasut 09 Dec '23

09 Dec '23

Add optional support for getopt() and in case this is enabled via GETOPT configuration option, implement support for 'bdinfo -a'. The 'bdinfo -a' behaves exactly like bdinfo and prints 'all' the bdinfo information. This is implemented in preparation for other more fine-grained options.

[PATCH v2 00/18] Support Firmware Handoff spec via bloblist
by Raymond Mao 08 Dec '23

08 Dec '23

Major changes: Update bloblist to align to Firmware Handoff spec v0.9 (https://github.com/FirmwareHandoff/firmware_handoff). Implement Qemu-Arm platform custom functions to retrieve the bloblist (aka. Transfer List) from previous loader via boot arguments when CONFIG_OF_BOARD option is enabled. If a board provides both custom functions for getting the bloblist and the address of external FDT, the FDT inside the bloblist will be prioritized during FDT setup. The patch set is tested with previous done TF-A/OP-TEE patches through a complete Firmware Handoff cycle (BL2, BL31, BL32, BL33).

[PATCH] sunxi: restore modified memory
by Andrey Skvortsov 06 Dec '23

06 Dec '23

On A64 with 2G of RAM words at following addresses were modified with 'aa55aa55' value: - 50000000 - 60000000 - 84000000 - 88000000 - 90000000 - A0000000 - A0000200 That made harder to pick memory range for persistent storage in RAM.
