Currently, there is no easy way to add or modify UEFI variables. In particular, bootmgr supports BootOrder/BootXXXX variables, it is quite hard to define them as u-boot variables because they are represented in a complicated and encoded format.
The new command, efishell, helps address these issues and give us more friendly interfaces:
- efishell boot add: add BootXXXX variable
- efishell boot rm: remove BootXXXX variable
- efishell boot dump: display all BootXXXX variables
- efishell boot order: set/display a boot order (BootOrder)
- efishell setvar: set an UEFI variable (with limited functionality)
- efishell dumpvar: display all UEFI variables
As the name suggests, this command basically provides a subset fo UEFI shell commands with simplified functionality.

The behavior is a bit unexpected:
=> efishell boot order 200 => efishell boot order 1: Boot00C8: (not defined) exit not allowed from main input shell.
I would expect 'efishell boot order' to take a 4 digit hexadecimal number and to do no conversion from decimal to hexadecimal.
I was also surprised to see 'exit not allowed from main input shell.'
