Tim Newsome 6f78eb1ec1 Add the first difference for 0.13 targets.
Just to confirm the 0.13 code takes a different path.

Albert Ou 9601429ac7 Use portable format specifier for size_t
This fixes a gcc warning [-Werror=format] on an i686-pc-linux-gnu host,
which defines size_t as unsigned int instead of long int.

Megan Wachs db2ec672b5 Merge pull request #4 from sifive/mwachs5-patch-sckdiv
Don't write SCKDIV when flashing
2016-11-30 10:19:54 -08:00
Megan Wachs ce49da9947 Don't write SCKDIV when flashing
The target may have already configured its clock to run at a higher frequency and would have set SCKDIV and other dividers at that time. Don't restore the SCKDIV to its default or the flash interface may run too fast and programming will fail.

Otherwise, the default value is fine and there is no need to write SCKDIV.

It's still really slow, at 854b/s, but it seems to work and it's a lot
of new code.

Tim Newsome e7a745ed3b Fix bug with slow targets.
Halting didn't work right in slow targets, because some code assumed the
register cache is valid before it was guaranteed to be.

Also made dbus_busy_delay and interrupt_high_delay grow faster, so that
on slow targets it takes less time to learn the correct values.

Tim Newsome 80e8101292 Make OpenOCD build using -Og.
With -Og gcc doesn't perform as many optimizations, and as a result
warns about some code that it wouldn't otherwise warn about.

These fixes all assign values to otherwise uninitialized variables.
