EHCI: zero out QH transfer overlay in ehci_submit_async()
ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI
specification suggests) which leads to the controller seeing the "token" field
as the previous call has left it, i.e.:
- if a timeout occured on the previous call (Active bit left as 1), controller
incorrectly tries to complete a previous transaction on a newly programmed
endpoint;
- if a halt occured on the previous call (Halted bit set to 1), controller just
ignores the newly programmed TD(s) and the function then keeps returning error
ad infinitum.
This turned out to be caused by the wrong orger of the arguments to the memset()
call in ehci_alloc(), so the allocated TDs weren't cleared either.
While at it, stop needlessly initializing the alternate next TD pointer in the
QH transfer overlay...

Previously, standalone applications were compiled with gcc flags that

fixups are performed on standalone applications.
Additionally, removing the gcc relocation flags results in the entry
point of applications residing at the base of the image. When
a standalone application was relocatable, the entry point was generally
located at an offset into the image which was confusing and prone to

The MPC5200 has a nasty problem that will cause silent data corruption
when performing unaligned 16 or 32 byte accesses when reading from the

be easily shown:
This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.

Remove continual revaluation of driver state from the core of the

Cost is more code space as loop variants are required for each set
of possible configurations. The loops are simpler however, so the
extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX

Unrolling the first copy loop iteration allows the TX buffer to be

Unrolling the last copy loop iteration removes testing for the
