Somehow I managed to slip a temporary build file into the tree.
Remove it and update the .gitignore file so it doesn't happen again.

The number of command arguments will always be 0 or more, so use
the right type in handlers. This has a cascading effect up through
the layers, but the new COMMAND_HANDLER macros prevented total chaos.
|
|
|
|
|
| |
By introducing the CMD_NAME macro, this parameter may be integrated
as args[-1] in command.[ch], without touching any other call sites.
|
|
|
|
|
|

By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.

ARM11 and newer cores include updated ETM modules. Recognize
their version codes and some key config differences. Sanity
checked on an OMAP2, with an ETM11RV r0p1 (ETMv3.1).
This still handles only scan chain 6, with at most 128 registers.
Newer cores (mostly, Cortex) will need to use the DAP instead.
Note that the newer ETM modules don't quite fit the quirky config
model of the older ones ... having more port widths is easy, but
the modes aren't the same. That still needs to change.
Fix a curious bug ... how did the register cache NOT get saved??

Now that nothing uses the old ETM handle any more, remove it.
Add minimal header tweaks, letting non-ARM7 and non-ARM9 cores
access ETM facilities.
Now ARM11 could support standard ETM (and ETB) access as soon as
it derives from "struct arm" ... its scanchain 6 is used access
the ETM, just like ARM7 and ARM9.
The Cortex parts (both M3 and A8) will need modified access methods
(via ETM init parameters), so they use the DAP. Our first A8 target
(OMAP3) needs that for both ETM and ETB, but the M3 ETM isn't very
useful without SWO trace support (it's painfully stripped down), so
that support won't be worth adding for a while.

Rename "struct armv4_5_common_s" as "struct arm". It needs
a bit more work to be properly generic, and to move out of
this header, but it's the best start we have on that today.
Add and initialize an optional ETM pointer, since that will
be the first thing that gets generalized.
The intent being: all ARMs should eventually derive from
this "struct arm", so they can reuse the current ETM logic.
(And later, more.) Currently the ARM cores that *don't* so
derive are only ARMv7-M (and thus Cortex-M3) and ARM11.

Removes forward declarations by moving command registration after
defintion of the command handlers.
|
| |
|
|
|
|
|
|

Add 'const' keyword to 'char *' parameters to allow command handlers to
pass constant string arguments. These changes allow the 'args' command
handler to be changed to 'const' in a subsequent patch.
|
|
|
|
|
|
|
|
|
|
|

Subsequent patches expect all command handlers to use a uniform
parameter naming scheme. In the entire tree, these two files used
standard 'argv' instead of our non-standard 'args'. This patch opts
to reduces the noise required to unify the command handlers, using
dominant 'args' form.
A future patch may be used to convert us back to the standard argv, but
that requires coordination with all developers to minimize disruptions.

Separates various groups of files to be built in logical succession.
In each layer, the core module (target.c, nand.c, etc.) is built _after_
their helper modules (e.g. image.c, nand_ecc.c) but _before_ any of
their drivers (e.g. arm966e.c, mx3_nand.c).
This allows problems introduced at the bottom of the stack to result
in build failures as soon as possible, as the helpers and core should
wrap portions of them.

Various cleanups of ETM related code.
- Saner error return paths
- Simplify arm7_9 init ... no need for extra zeroing!
- Shrink some lines
- Tweak some diagnostics
- Use shorter name for ETM struct type.
- Don't exit()
and similar. The diagnostics look forward to having
this ETM code work with more than just ARM7/ARM9.

Start switching MMU handling over to a more sensible scheme.
Having an mmu() method enables MMU-aware behaviors. Not having
one kicks in simpler ones, with no distinction between virtual
and physical addresses.
Currently only a handful of targets have methods to read/write
physical memory: just arm720, arm920, and arm926. They should
all initialize OK now, but the arm*20 parts don't do the "extra"
stuff arm926 does (which should arguably be target-generic).
Also simplify how target_init() loops over all targets by making
it be a normal "for" loop, instead of scattering its three parts
to the four winds.

This patch introduced a bug preventing flash writes from working
on Cortex-M3 targets like the STM32. Moreover, it's the wrong
approach for handling no-MMU targets.
The right way to handle no-MMU targets is to provide accessors
for physical addresses, and use them everywhere; and any code
which tries to work with virtual-to-physical mappings should use
a identity mapping (which can be defaulted).
And ... we can tell if a target has an MMU by seeing if it's
got an mmu() method. No such methood means no MMU.

It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

This patch changes the duration_* API in several ways. First, it
updates the API to use better names. Second, string formatting has
been removed from the API (with its associated malloc). Finally, a
new function added to convert the time into seconds, which can be
used (or formatted) by the caller. This eliminates hidden calls to
malloc that require associated calls to free().
This patch also removes the useless extern keyword from prototypes,
and it eliminates the duration_t typedef (use 'struct duration').
These API also allows proper error checking, as it is possible for
gettimeofday to fail in certain circumstances.
The consumers have all been chased to use this new API as well, as
there were relatively few cases doing this type of measurement.
In most cases, the code performs additional checks for errors, but
the calling code looks much cleaner in every case.

Resolve serious bug inserted by the "target: require working
area for physical/virtual addresses to be specified" patch.
It forced use of (invalid) virtual addresses when the MMU
was disabled, and vice versa.
Observed to break at least Cortex-M3, ARM926, ARM7TDMI whenever
work areas are used, such as during bulk writes to flash, DDR2,
SRAM, and so on.
Also, fix overlong lines and whitespace goofs.

Move various embedded target structs to the beginnings of
their containers ... pretty much the way C++ or Obj-C
would for single inheritance.
This shrinks code that accesses those embedded structs by
letting common offsets use smaller instructions. Sample
before/after sizes (on amd64):
17181 312 0 17493 4455 arm920t.o
16810 312 0 17122 42e2 arm920t.o
Where the "after" is the smaller number, with this patch
over the ones leveraging that embedding knowledge.
