From mboxrd@z Thu Jan 1 00:00:00 1970 From: Martyn Welch Date: Tue, 6 Nov 2018 12:23:53 +0000 Subject: [U-Boot] [PATCH v3] Ability to modify distro boot filename Message-ID: <20181106122353.9136-1-martyn.welch@collabora.co.uk> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add in the ability to modify the distro boot filename. Whilst not immediately useful in normal usage, it allows an alternative configuration to be provided when other u-boot functionality is used, such as bootcount limit, to fallback to an alternative boot configuration. In this case we can follow the same boot path as for normal boot, just using an alternatively named configuration file. For example, by providing the following `altbootcmd` when bootcount is in use: altbootcmd=setenv boot_extlinx_conf extlinux-rollback.conf; \ run distro_bootcmd Signed-off-by: Martyn Welch --- Changes in v3: - Moving path to config variable, rename `boot_syslinux_conf` Changes in v2: - Moving config variable from `boot_config` to `boot_extlinux_conf` include/config_distro_bootcmd.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/include/config_distro_bootcmd.h b/include/config_distro_bootcmd.h index 373fee78a9..5838eb3477 100644 --- a/include/config_distro_bootcmd.h +++ b/include/config_distro_bootcmd.h @@ -355,15 +355,16 @@ "boot_script_dhcp=boot.scr.uimg\0" \ BOOTENV_BOOT_TARGETS \ \ + "boot_syslinux_conf=extlinux/extlinux.conf\0" \ "boot_extlinux=" \ "sysboot ${devtype} ${devnum}:${distro_bootpart} any " \ - "${scriptaddr} ${prefix}extlinux/extlinux.conf\0" \ + "${scriptaddr} ${prefix}${boot_syslinux_conf}\0" \ \ "scan_dev_for_extlinux=" \ "if test -e ${devtype} " \ "${devnum}:${distro_bootpart} " \ - "${prefix}extlinux/extlinux.conf; then " \ - "echo Found ${prefix}extlinux/extlinux.conf; " \ + "${prefix}${boot_syslinux_conf}; then " \ + "echo Found ${prefix}${boot_syslinux_conf}; " \ "run boot_extlinux; " \ "echo SCRIPT FAILED: continuing...; " \ "fi\0" \ -- 2.11.0
