[PATCH v2 1/4] ARM: dts: imx: Make DRAM coding GPIOs available before relocation on Data Modul i.MX8M Mini/Plus eDM SBC
by Marek Vasut 30 Nov '24

30 Nov '24

The DRAM configuration GPIO straps must be accessible in SPL and before relocation because the GPIOs are sampled both in U-Boot SPL as well as early on in U-Boot proper. The already present bootph-pre-ram DT property made the GPIO controllers available in SPL, but not early on in U-Boot proper, which made gpio_request_list_by_name_nodev() in board dmo_get_memcfg() fail. Add missing bootph-some-ram DT property to all GPIO controllers which are referenced in dmo,ram-coding-gpios DT property to make those GPIO controllers available early in U-Boot proper as well.

[PATCH v2] test/cmd/wget.c: move net_test_wget() to the cmd test suite
by Jerome Forissier 29 Nov '24

29 Nov '24

Since net_test_wget() is testing a command and is in test/cmd it should be in the 'cmd' test suite, not 'lib'. Saving and restoring the values of the environment variables that the test manipulates is necessary to avoid a regression when running the whole ut test suite.

[PATCH] efi_loader: Add U-Boot memory to the EFI memory map
by Ilias Apalodimas 29 Nov '24

29 Nov '24

This code was removed when the EFI subsystem started using LMB calls for the reservations. In hindsight it unearthed two problems. The e820 code is adding u-boot memory as EfiReservedMemory while it should look at what LMB added and decide instead of blindly overwriting it. Thew reason this worked is that we marked that code properly late, when the EFI came up. But now with the LMB changes, the EFI map gets added first and the e820 code overwrites it. The second problem is that we never mark SetVirtualAddressMap as runtime code, which we should according to the spec. Until we fix this this hack can't go away, at least for architectures that *need* to call SVAM. More specifically x86 which currently requires SVAM, sets the NX bit for pages not marked as *_CODE. So unless we do that late, it will crash trying to execute from non-executable memory. Notably arm64 disables it explicitly if the VA space is > 48bits, so doesn't suffer from any of these problems. This doesn't really deserve a fixes tag, since it brings back a hack to rememdy a sitation that was wrong long before that commit, but in case anyone hits the same bug ...

Add support for the DH electronics i.MX6DL DHCOM SoM and a PDK2 evaluation board. The evaluation board features three serial ports, USB OTG, USB host with an USB hub, Fast or Gigabit ethernet, eMMC, uSD, SD, analog audio, PCIe and HDMI video output. All of the aforementioned features except for mSATA are supported, mSATA is not available on i.MX6DL and is only available on DHCOM populated with i.MX6Q SoC which is already supported upstream.

[PATCH v2] ARM: imx: Replace YModem with SDP on Data Modul i.MX8M Mini eDM SBC SPL
by Marek Vasut 29 Nov '24

29 Nov '24

The YModem support in SPL was never really used on this device, the SDP support is much more convenient on i.MX8M Mini based hardware. Replace the YModem support with SDP support. The SDP can be utilized by forcing the board into SDP boot mode by grounding test point right next to silkscreen label U30, and then by using mfgtools 'uuu -brun spl flash.bin' once the device enumerates on host system USB bus. The SDP capable USB port is available on the USB micro-B port on the base board.

[PATCH 1/4] ARM: dts: imx: Make DRAM coding GPIOs available in all phases on Data Modul i.MX8M Mini/Plus eDM SBC
by Marek Vasut 29 Nov '24

29 Nov '24

The DRAM configuration GPIO straps must be accessible in all boot phases because the GPIOs are sampled both in U-Boot SPL as well as early on in U-Boot proper. The already present bootph-pre-ram DT property made the GPIO controllers available in SPL, but not early on in U-Boot proper, which made gpio_request_list_by_name_nodev() in board dmo_get_memcfg() fail. Add missing bootph-all DT property to all GPIO controllers which are referenced in dmo,ram-coding-gpios DT property to make those GPIO controllers available early in U-Boot proper as well.
