THe RVT data includes a major and minor version in its header parameter. Add a new command to print this out. Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> --- Unfortunately there doesn't seem to be a way to get the minor version of the hab ROM. While there is a get_version function pointer in the vector table it's documented to only be valid during the ROM phase and a quick hack to try and call it on my board always returned 1 :/. arch/arm/include/asm/mach-imx/hab.h | 1 + arch/arm/mach-imx/hab.c | 21 +++++++++++++++++++++ 2 files changed, 22 insertions(+)
