Randall Spangler 7ecd1d6d3c Add system_is_locked() to prevent sysjump on consumer systems ...

This returns true when both HW and SW write protect are enabled.

Once WP is enabled, sysjump will be locked out.

system_is_locked() can be used to gate other dangerous-ish commands too.

sysinfo -> unlocked, copy A
sysjump B -> works
flashwp lock

(make sure flashinfo shows WP asserted and flash locked; note there is a
 HW bug on proto1 which makes this flaky)
sysinfo -> locked, copy A
sysjump B -> fails
(remove WP screw)

flashwp unlock
