It is easier and less error-prone to use super() when the parent type is needed. Update binman to remove the type names. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

x86 CPUs start up in 16-bit mode, even if they are 32-bit CPUs. This code
|
|
must be placed in the top 64KB of the ROM. The reset code jumps to it. This
|
|
entry holds that code. It is typically placed at offset
|
|
CONFIG_SYS_X86_START16. The code is responsible for changing to 32-bit mode
|
|
and jumping to U-Boot's entry point, which requires 32-bit mode (for 32-bit
|
|
U-Boot).
|
|
|
|
For 64-bit U-Boot, the 'x86_start16_spl' entry type is used instead.
