From 9ee9bdd2f9e69df816d313d23b50a563c0869428 Mon Sep 17 00:00:00 2001 From: Evgeniy Didin Date: Mon, 27 Jan 2020 15:22:27 +0300 Subject: Introduce ARCv2 architecture related code This patch is an initial bump of ARC-specific code which implements the ARCv2 target(EMSK board) initializing routine and some basic remote connection/load/continue functionality. Changes: 03.12.2019: -Add return value checks. -Using static code analizer next fixes were made: Mem leak in functions: arc_jtag_read_memory,arc_jtag_read_memory, arc_jtag_write_registers, arc_jtag_read_registers, jim_arc_add_reg_type_flags, jim_arc_add_reg_type_struct, arc_build_reg_cache, arc_mem_read. Dead code in "arc_mem_read"; In arc_save_context, arc_restore_context correct arguments in"memset" calls. In "build_bcr_reg_cache", "arc_build_reg_cache" check if list is not empty. 29.12.2019 -Moved code from arc_v2.c to arc.c -Added checks of the result of calloc/malloc calls -Reworked arc_cmd.c: replaced spagetty code with functions -Moved to one style in if statements - to "if(!bla)" -Changed Licence headers 22.01.2020 -Removed unused variables in arc_common -Renamed register operation functions -Introduced arc_deinit_target function -Fixed interrupt handling in halt/resume: * add irq_state field in arc_common * fix irq enable/disable calls ( now STATUS32 register is used) -Switched from buf_set(get)_us32() usage to target_buffer_set(get)_u32() -Made some cleanup 30.01.2020 -Removed redundant arc_register struct, moved target link to arc_reg_desc -Introduced link to BCR reg cache in arc_common for freeing memory. -Now arc_deinit_target frees all arc-related allocated memory. Valgrind shows no memory leaks. -Inroduced arch description in arc.c 01.02.2020 -Remove small memory allocations in arc_init_reg. Instead created reg_value and feature fields in arc_reg_desc. -Add return value for arc_init_reg() func. -Replaced some integer constants(61,62,63) with defines. -Removed redundant conversions in arc_reg_get_field(). -Moved iccm/dccm configuration code from arc_configure() to separate functions. 19.02.2020 -Change sizeof(struct) to sizeof(*ptr) in allocations -Changed if/while(ptr != NULL) to if/while(ptr) -Removed unused variables from struct arc_jtag -Add additional structs to arc_reg_data_type to reduce amount of memory allocations calls and simplifying memory freeing. -Add helper arc_reg_bitfield_t struct which includes reg_data_type_bitfield object and char[] name. Reduces memory allocations calls. -Add limit for reg_type/reg_type_field names(20 symbols). -Add in jim_arc_add_reg_type*() functions additional argnument checks(amount of field/name size). -In jim_arc_add_reg_type*() reduced amount of memory allocations. -Cleanup of jim_arc_add_reg_type*() functions. -For commands update ".usage" fields according docopt. -Cleanup in arc_jtag.c -Renamed functions which require jtag_exeutre_queue() to arc_jtag_enque_*() -Add arc_jtag_enque_register_rw() function, which r/w to jtag ir/dr regs during regiter r/w. 24.02: -Change include guards in arc* files according coding style -Remove _t suffix in struct arc_reg_bitfield_t -Some cleanup Change-Id: I6ab0e82b12e6ddb683c9d13dfb7dd6f49a30cb9f Signed-off-by: Evgeniy Didin Cc: Alexey Brodkin Reviewed-on: http://openocd.zylin.com/5332 Tested-by: jenkins Reviewed-by: Oleksij Rempel --- src/target/target.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/target/target.c') diff --git a/src/target/target.c b/src/target/target.c index 688d318..1ba4e09 100644 --- a/src/target/target.c +++ b/src/target/target.c @@ -111,6 +111,7 @@ extern struct target_type stm8_target; extern struct target_type riscv_target; extern struct target_type mem_ap_target; extern struct target_type esirisc_target; +extern struct target_type arcv2_target; static struct target_type *target_types[] = { &arm7tdmi_target, @@ -146,6 +147,7 @@ static struct target_type *target_types[] = { &riscv_target, &mem_ap_target, &esirisc_target, + &arcv2_target, #if BUILD_TARGET64 &aarch64_target, &mips_mips64_target, -- cgit v1.1
