Subject: [PATCH 1/2] gdbserver/xtensa: drop xtensa_usrregs_info
|
||||
|
||||
xtensa_usrregs_info refers to undefined variables xtensa_num_regs and
|
||||
xtensa_regmap. Drop xtensa_usrregs_info and replace pointer to usrregs
|
||||
in regs_info with NULL since all registers are read/set through regsets.
