[PATCH v6 0/9] Add EFI HTTP boot support
by Masahisa Kojima 16 Oct '23

16 Oct '23

This series adds the EFI HTTP boot support. User can add the URI device path with "efidebug boot add" command. efibootmgr handles the URI device path, download the specified file using wget, mount the downloaded image with blkmap, then boot with the default file(e.g. EFI/BOOT/BOOTAA64.EFI) by selecting automatically created boot option when the new disk is detected. This version still does not include the test. To enable EFI HTTP boot, we need to enable the following Kconfig options. CONFIG_CMD_DNS CONFIG_CMD_WGET CONFIG_BLKMAP CONFIG_EFI_HTTP_BOOT On the Socionext Developerbox, enter the following commands then debian installer is downloaded into "loadaddr" and installer automatically starts. => dhcp => setenv serverip 192.168.1.1 => efidebug boot add -u 3 debian-netinst http://ftp.riken.jp/Linux/debian/debian-cd/12.1.0/arm64/iso-cd/debian-12.1.… => efidebug boot order 3 => bootefi bootmgr Note that this debian installer can not proceed the installation bacause RAM disk of installer image is not recogniged by the kernel.

[PATCH] eeprom: at24: add ST M24C32-D Additional Write lockable page support

The ST M24C32-D behaves as a regular M24C32, except for the -D variant which uses up another I2C address for Additional Write lockable page. This page is 32 Bytes long and can contain additional data. Add entry for it, so users can describe that page in DT. Note that users still have to describe the main M24C32 area separately as that is on separate I2C address from this page. >From Linux kernel commit: 4791146e9055 ("eeprom: at24: add ST M24C32-D Additional Write lockable page support") Signed-off-by: Marek Vasut <marex(a)denx.de> --- Cc: "NXP i.MX U-Boot Team" <uboot-imx(a)nxp.com> Cc: Fabio Estevam <festevam(a)gmail.com> Cc: Stefano Babic <sbabic(a)denx.de> Cc: u-boot(a)dh-electronics.com --- drivers/misc/i2c_eeprom.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/misc/i2c_eeprom.c b/drivers/misc/i2c_eeprom.c index bdd7e018cc6..e1d0b8f918a 100644 --- a/drivers/misc/i2c_eeprom.c +++ b/drivers/misc/i2c_eeprom.c @@ -227,6 +227,13 @@ static const struct i2c_eeprom_drv_data atmel24c32_data = { .offset_len = 2, }; +static const struct i2c_eeprom_drv_data atmel24c32d_wlp_data = { + .size = 32, + .pagesize = 32, + .addr_offset_mask = 0, + .offset_len = 2, +}; + static const struct i2c_eeprom_drv_data atmel24c64_data = { .size = 8192, .pagesize = 32, @@ -266,6 +273,7 @@ static const struct udevice_id i2c_eeprom_std_ids[] = { { .compatible = "atmel,24c16a", (ulong)&atmel24c16a_data }, { .compatible = "atmel,24mac402", (ulong)&atmel24mac402_data }, { .compatible = "atmel,24c32", (ulong)&atmel24c32_data }, + { .compatible = "atmel,24c32d-wl", (ulong)&atmel24c32d_wlp_data }, { .compatible = "atmel,24c64", (ulong)&atmel24c64_data }, { .compatible = "atmel,24c128", (ulong)&atmel24c128_data }, { .compatible = "atmel,24c256", (ulong)&atmel24c256_data }, -- 2.42.0

From: Ivaylo Ivanov <ivo.ivanov(a)null.net> Currently, mach-apple assumes we're working with M1/M2. Make room for adding support for other Apple SoCs by moving everything from the M1/M2 SoC family in "mach-apple/" into "mach-apple/m1/".
