in line 1391, get_stm32l4_bank_type_str(bank) will always output the same
value "Flash single" since the variable stm32l4_info->dual_bank_mode is false
by default, stm32l4_info->dual_bank_mode will be set correctly afterward
in the switch case at line 1467
thus the need to remove the usage of get_stm32l4_bank_type_str(bank) before
stm32l4_info->dual_bank_mode initialization.

JEP106 encodes JEDEC-assigned manufacture code as:
a) a sequence of zero or more escape codes 0x7f;
b) an odd-parity bit of the next 7 bits;
c) 7 bits.
The same code is often represented as a single value composed by
the logical OR between:
- the number of escape codes in a), shifted left by 7 positions;
- the 7 bits in c).
This is the preferred packed representation used by this change.
Currently there are only two uses of JEP106 in openocd to get the
manufacturer name:
- to decode the JTAG IDCODE of each TAP, where the JEP106 code is
already packed as in the preferred representation above in bits
IDCODE[11:1];
- to decode the ARM CoreSight PIDR register, where the JEP106 code
is split in 3 parts:
= PIDR3[3:0], corresponding to bits [10:7] of the packed code;
= PIDR2[2:0], corresponding to bits [6:4] of the packed code;
= PIDR1[7:4], corresponding to bits [3:0] of the packed code.
Wrap the existing JEP106 decode function in a simpler API using
the packed code.
Simplify the callers by skipping the bit unpacking.
Change the manufacturer code in CoreSight table dap_partnums[] to
match the packed representation, by removing the always-one bit 7
erroneously taken from PIDR bit JEDEC and included in the former
table.

In case of multi-word commands, the command dispatcher is nested
called at each word during command name parsing.
The improper position of the call to script_debug() causes the
command line to be logged once at each parsed word.
In the example of command "cpu arm disassemble 0" the full command
is logged three times for "cpu", "arm" and "disassemble":
Debug: 656617 61843 command.c:201 script_debug(): command - cpu arm disassemble 0
Debug: 656618 61843 command.c:201 script_debug(): command - cpu arm disassemble 0
Debug: 656619 61843 command.c:201 script_debug(): command - cpu arm disassemble 0
Call script_debug() only when the parsing is terminated and the
command handler is going to be executed.

The command 'step' accepts an optional parameter 'address' to run
the step-by-step execution from an address different from current
program counter.
When OpenOCD sets the new program counter value in the register
cache, it doesn't flag it as dirty. The following call to function
armv7m_restore_context() does not propagate the new value of the
program counter to the target. This cause the target to continue
from the old program counter value, ignoring the user's request.
It is hard to notice the issue if the target is halted in an idle
loop! In fact the default mode to operate step-by-step is to set a
breakpoint to the following instruction and resume execution. In
the idle loop the CPU will pass through the breakpoint whatever
the resume address is. User will find the target halting at the
instruction following 'address' which is consistent with the
expected behaviour of command 'step address'.
To verify the issue on an STM32F4, use a dummy code in SRAM:
halt
mww 0x20000000 0xbf00bf00
mww 0x20000004 0xbf00bf00
mww 0x20000008 0xe7fcbf00
arm disassemble 0x20000000 6
0x20000000 bf00 nop
0x20000002 bf00 nop
0x20000004 bf00 nop
+--> 0x20000006 bf00 nop
| 0x20000008 bf00 nop
+-<- 0x2000000a e7fc b #0x20000006
resume 0x20000006
halt
step 0x20000000
the target doesn't halt because it is in the loop from 0x20000006
to 0x2000000a. The 'step 0x20000000' did not changed the program
counter so the temporary breakpoint at 0x20000002 is never hit.
Then:
halt
step 0x20000008
target halted ...
... pc: 0x2000000a
gives the feeling that only the instruction at 0x20000008 has been
executed, but actually the whole loop has been executed from the
place 'halt' stopped the execution till the breakpoint at the
instruction following 0x20000008.
Flag the program counter cached value as 'valid' and 'dirty' to
force armv7m_restore_context() to update the target's register.

Commit 89f07325f2 ("stlink: Set speed before entering JTAG/SWD

in the JTAG/SWD mode. This to initiate the communication with the
speed selected by the user.
But SWIM doesn't allow setting the speed before entering in SWIM
mode. The resulting error causes OpenOCD to quit.
The problem only happens with stlink-v3, due to the different way
to set the adapter speed on different stlink versions.
Set the speed before entering in the mode only for JTAG and SWD
modes.

Commit ac22cdc573 ("target/adiv5: Large Physical Address
Extension") reads the register MEM_AP_REG_CFG and keeps it in a
new field of struct adiv5_ap. The test on LE bit (Large Extension)
is used to identify if mem_ap addresses are 32 or 64 bits.
But the register MEM_AP_REG_CFG is only read during mem_ap_init(),
that is called only when the AP is used as a target debug AP or if
a target mem_ap is attached to that AP.
The openocd commands '<dapname> baseaddr', '<dapname> info' and
'dap info' can be executed on AP that has not been associated yet
to a target, thus executed without any knowledge of MEM_AP_REG_CFG
value. The initialization to ADI_BAD_CFG causes openocd to always
use 32 bit mode on un-associated APs.
Verify if MEM_AP_REG_CFG has not been read and eventually read it.
In case of 32 bits mode AP, MEM_AP_REG_BASE64 is defined as 'RES0'
(reserved, but readable); the code can queue both the read of
MEM_AP_REG_CFG and MEM_AP_REG_BASE64, before knowing if the former
is required. This speeds-up the operation.
Rename ADI_BAD_CFG as MEM_AP_REG_CFG_INVALID.

In both arm ADIv5 and ADIv6 documentation, for both Class 0x1 and
Class 0x9 ROM tables, the offset field from ROM tables is supposed
to be a signed value: "Negative values of OFFSET are permitted,
using two’s complement."
The commit ac22cdc573 ("target/adiv5: Large Physical Address
Extension") extends to 64 bits the addresses while managing the ROM
tables. The offset is read as unsigned and in the former 32 bits
implementation the wrap-around was hiding the need for converting
the offset to signed. The new implementation requires the proper
cast to the offset.
On a STM32F411, without this fix the ROM table dump is incorrectly
reporting addresses out of the 32 bit bus range:
MEM-AP BASE 0xe00ff003
Valid ROM table present
Component base address 0xe00ff000
Peripheral ID 0x00000a0411
Designer is 0x0a0, STMicroelectronics
Part is 0x411, Unrecognized
Component class is 0x1, ROM table
MEMTYPE system memory present on bus
ROMTABLE[0x0] = 0xfff0f003
Component base address 0x1e000e000
^^^^^^^^^^^
Cast the offset before adding it to the base address of the ROM
table.
