2012-10-28flash: update stm32 flash driver versionsSpencer Oliver
Seems ST have changed the ref manual (RM0313 rev1) and reverted to using letters rather than numbers for the stm32f3x family.

2012-10-08stm32f1x: Increase options erase timeoutAndreas Fritiofson
The erase time for the option byte page is not directly specified but is assumed to be the same as the other pages (or mass erase) which is 20 to 40 ms. The current timeout value is 10 which means 10 ms plus the time to poll the status flag that many times. With faster interfaces or drivers (such as when using the ftdi driver instead of the ft2232 driver) the adapter delay is not enough in some cases, unless the jtag freq is reduced as a workaround. The result is a "timed out waiting for flash" error when trying to write the options. Increase the timeout to a minimum of 100 ms, which is in line with the other erase timeouts. Also make defines of both the erase and the program timeouts.

2012-08-01flash: stm32f1x: Pad odd byte writes early to avoid 16-bit writesAndreas Fritiofson
For odd byte counts, stm32x_write() pads the last byte and writes it using a discrete 16-bit access. The stlink debugger can't issue 16-bit writes so it fails for odd byte writes. This patch changes stm32x_write() to pad odd byte writes into a new buffer and use the normal code path with a single block write. The fallback path, when working area cannot be allocated, has to use 16-bit writes though which means that sufficient working area is required for stlink and odd byte writes.

2011-10-09stm32f1x: use async algorithm in flash programming routineAndreas Fritiofson
Let the target algorithm be running in the background and buffer data continuously through a FIFO. This reduces or removes the effect of latency because only a very small number of queue executions needs to be done per buffer fill. Previously, the many repeated target state changes, register accesses (really inefficient) and algorithm uploads caused the flash programming to be latency bound in many cases. Now it should scale better with increased throughput. Signed-off-by: Andreas Fritiofson <andreas.fritiofson@gmail.com>
