Browse Source 
sideleg and sedeleg csrs are not part of riscv isa spec
anymore, these csrs were part of N extension which
is removed from the riscv isa specification.

These commits removed all traces of these csrs from
riscv spec (https://github.com/riscv/riscv-isa-manual) -

commit f8d27f805b65 ("Remove or downgrade more references to N extension (#674)")
commit b6cade07034d ("Remove N extension chapter for now")
