Paul Fertser f43c23090e rlink: fix speed table generation
The speed table generation (by using explicit
make -f Makefile.rlink) was broken since
865efd828a Dec 2 2009 which did a bunch of
renaming and included hand-editing of a generated rlink_speed_table.c file.

This patch is compile-tested, i.e. the new generated rlink_speed_table.c
links fine with the rlink driver.

Paul Fertser afca2e817d cortex_m, hla_target: do not try asserting SRST if it's not present
This should cover all the cases when RESET_SRST_NO_GATING is set
without RESET_HAS_SRST. This might happen when RESET_SRST_NO_GATING is
automatically set by a target code (and not from tcl).

However, there're some other places (mips_m4k, arm7_9_common) where
adding RESET_SRST_PULLS_TRST would lead to trying to use SRST even if
it's not present. Currently it's impossible for the user to enable
that flag without enabling SRST.

Paul Fertser 2aada5b8d9 targets: fix target_type name for Cortex-A targets
Commit d9ba56c295 did a bunch of
renaming of cortex_a8 to cortex_a, including the names in config
files. However that introduced a regression as the name in target_type
struct remained unchanged.

This adds the last missing bit: actual renaming of the target name as
understood by OpenOCD.

Also change the (hopefully) last instance of using it in the supplied
config files, namely from imx6.cfg.

in gdb event callback.  It will execute event statements in config
files twice.

Matt Dittrich ad1c9cdbcb flash/nor: add lpc4300 variant to lpc2000 driver
This patch adds flash programming support for internal flash of the
LPC43x2/3/5/7 part, tested on a LPC4337 (also tested on a LPC1768
and LPC2468). It should also work with LPC1800's with onchip flash.
The "base" parameter of the "flash bank" command is now significant
for the lpc4300 variant and required to determine the bank number
parameter needed by the IAP routines.

NOTE: I could only program flash successfully when the chip is powered
with "P2_7" pulled low to put it in ISP mode.  When running from flash
(and not the ISP ROM), the target fails to halt and the sector erase
fails. This is similar to the behavior I remember when trying out the
spifi driver on a LPC4350... lots of power cycles to make progress, one
To burn, one to run.  So I am not confident my config is set up correctly.

R. Steve McKown d7646942f2 Support newer OSBDM firmware
OSBDM: add new VID:PID implemented in OSJTAG/OSBDM firmware somewhere
between versions 30.13 and 31.21.  PFLASH programming works with this
patch, tested on a Freescale Kinetis TWR-K20D72M using its onboard OSBDM
JTAG adapter.

Note: flash program testing required hacking kinetis_write() to force
longword programming, as the FTFL program section commands formulated by
kinetis_write() currently fail on this board's PK20DX256VLL7 processor.

Salvador Arroyo 9695564e63 mips: m4k alternate pracc code. Patch 4
Now all the functions with only fetch accesses are modified.
The same delay between scans has been added to mips32_pracc_fastdata_xfer(), it should work
at the same scan rates as the other pracc functions, but it needs higher scan_delays
to work.

Salvador Arroyo d5e564625f mips: m4k alternate pracc code. Patch 3
Functions mips32_pracc_read_mem(), mips32_cp0_read() and mips32_pracc_read_regs() are now modified.
mips32_cp0_read() is very similar to mips32_read_u32() with one store access.
mips32_pracc_read_regs() is the only function that can not be executed from only one queue.
Now this function is modified to use reg8, it saves all the registers but does not restore reg8.
To remedy this, mips_ejtag_config_step() is called after mips32_save_context() in
mips_m4k_debug_entry(). Function mips_ejtag_config_step() is modified to use reg8 and
restore it from ejtag info instead of using DeSave for save/restore.

Salvador Arroyo 37c28903a1 mips: m4k alternate pracc code. Patch 2
Each pracc function defines a variable ctx of type struct pracc_queue_info.
To simplify the code tree auxiliary functions are defined: pracc_queue_init(), pracc_add() and
pracc_queue_free().
The second parameter in pracc_add() is the store address if the instruction is a store at dmseg,
otherwise it should be 0.
The code is executed by mips32_pracc_queue_exec(). If ejtag_info->mode is 0 mips32_pracc_exec()
is called and it should work like with current code.
To generate the delay between scans the number of clock ticks are calculated with the help of
jtag_get_speed_khz(). Due to delays in the execution of each single ftdi instruction the number of ticks
are higher as it should be, specially at higher scan rates.
mips32_pracc_read_u32() should now work with the new code.

Salvador Arroyo 109f37c161 mips: m4k alternate pracc code. Patch 1
This patch and the following patches define another way of doing processor access without the need to read back
the pracc address as needed in current pracc code.
Current pracc code is executed linearly and unconditionally. The processor starts execution at 0xff200200
and the fetch address is ever incremented by 4, including the last instruction in the delay slot of the branch to start.
Most of the processor accesses are fetch and some are store accesses.
After a previous patch regarding the way of restoring registers (reg8 and reg9), there are no load processor accesses.
The pracc address for a store depends only on the store instruction given before.
m4k core has a 5 stage pipeline and the memory access is done in the 3rth stage. This means that the store access
will not arrive immediately after a store instruction, it appears after another instruction enters the pipeline.
For reference: MD00249 mips32 m4k manual.
A new struct pracc_queue_info is defined to help each function in generating the code. The field pracc_list holds in the
lower half the list of instructions and in the upper half the store addressess, if any. In this way the list can be used by
current code or by the new one to generate the sequence of pracc accesses.
For every pracc access only one scan to register "all" is used by calling the new function mips_ejtag_add_scan_96().
This function does not call jtag_execute_queue(), all the scans needed can be queued before calling for execution.
The pracc bit is not checked before execution, is checked after the queue has been executed.
Without calling the wait function the code works much faster, but the scan frequency must be limited. For pic32mx
with core clock at 4Mhz works  up to 600Khz and with 8Mhz up to 1200. To increase the scan frequency a delay
between scans is added by calling jtag_add_cloks().
A time delay in nano seconds is stored in scan_delay, a new field in ejtag_info, and a handler is provided for it.
A mode field is added to ejtag_info to hold the working mode. If a time delay of 2ms (2000000 ns) or higher is set,
current code is executed, if lower, new code is executed.
Initial default values are set in function mips32_init_arch_info. A reset does not change this settings.

Ben Nahill 2cb486213e topic: STM32W support added to em357 driver
The em357 driver only supported one page configuration (192k in 96 2048k)
pages. This is fine for em357 chips since that's the size they have, but
ST's STM32W chips (pretty much the same) have different flash
configurations available (64, 128, 192, 256k). I can't find anywhere
that would indicate the size of the chip anywhere in memory so the
selection must be manual, using the 'size' parameter. For backwards
compatibility, any size not known to be in use defaults to the 192k
configuration. I don't have any em357 devices to test, but I also found
that I had to re-assert the FPEC clock enable before performing an
erase. This is a single line and shouldn't break any configurations.

My testing so far has only been with a 64k device with 8k of RAM.
