Harunobu Kurokawa 4c033eb074 rpi-cmdline, rpi-u-boot-src: Support USB boot ... The Raspberry Pi 4 board can boot the image from USB memory. But current meta-raspberrypi supports only SD boot. This commit allows switching SD boot to other device. For example, if you want to use USB boot, please define the following parameters in your conf/local.conf file. CMDLINE_ROOT_PARTITION = "/dev/sda2" BOOT_MEDIA = "usb" v4: Update extra-build-config.md to explain more detail for new variable. v3: Changed variable name to "BOOT_MEDIA" (was "BOOT_DEVTIPE"). v2: Set existing microSD parameter as default. User can overwrite some parameters. Signed-off-by: Harunobu Kurokawa <harunobu.kurokawa.dn@renesas.com>		2023-12-13 16:43:59 +02:00
