[U-Boot] [PATCH 1/1] cmd: add exception command
by Heinrich Schuchardt 24 Apr '19

24 Apr '19

The 'exception' command allows to test exception handling. This implementation supports ARM, x86, RISC-V and the following exceptions: * 'breakpoint' - prefetch abort exception (ARM 32bit only) * 'unaligned' - data abort exception (ARM only) * 'undefined' - undefined instruction exception Signed-off-by: Heinrich Schuchardt <xypron.glpk(a)gmx.de> --- v2: Split architecture specific code into separate files.
