This disables any usage of the on-device R/W cache since all device
cache maintenance functions are compiled out under RTEMS leaving no way
to flush the cache before system reset and making data loss possible.
The i.MX6UL (and some others from the i.MX family) have shared MDIO
lines for multiple FFECs. This patch allows to use the MDIO interface
from another Ethernet controller.
Note that you have to make sure that the FFECs are initialized in the
right order. Normally that can be done via FDT.
With the previous fix, it could happen that the end of the packet hasn't
been flushed. For example assume the following addresses:
ds_addr: 0x81c804A
ds_len: 0x57
In that case the data ends at 0x81c80a1. But due to the rounding the
area from 0x81c8040 to 0x81c80a0 would have been flushed.
This fix now first calculates the start and end address, aligns these
addresses and then recalculates the len that has to be flushed.
Update #4180
Update the host frame interval after a device connection. Select also
the FS/LS PHY clock. It is not clear if this works on all platforms.
Update #3910.
- cpusets and SMP are currently not supported in libbsd for RTEMS
- Disable the ifc_cpus context variable and replace its usage,
essentially hard-coding for cpu 0
Some targets support only flushing or invalidating complete cache lines.
In this cases misaligned buffers might lead to unexpected results. This
patch adds a flag that allows drivers to signal to the bus dma driver
that it is OK to round a buffer to the next full cache line. That's for
example necessary if a driver wants to send out 14 byte via a USB DMA.
Only the driver knows whether these 14 bytes are located in an otherwise
unused cache line aligned buffer.
There is a bug in the #ifdef regarding FDT so this file hasn't been
compiled. If that bug is solved, the driver doesn't work for some other
reason.
With the FDT-bug the driver hasn't been used by anyone. So just remove
it again.
This is not a nice solution but it should work on all chips. As soon as
FreeBSD has a nice solution via the USB PHY driver, this should be
replaced.
Update #3869.
The rtems_bsd_mmcsd_attach_worker acquired the bus without releasing it.
If a MMC device has multiple hardware partitions (like eMMC which
typically has at least one boot partition) the
rtems_bsd_mmcsd_attach_worker would try to acquire the bus multiple
times. This doesn't work.
Doing it right would mean to acquire and release the bus for each
access which would have an performance impact. Beneath that it would
mean that partition switching has to be supported by the RTEMS code too.
There is currently no known use case where the access would be
necessary. Therefore this patch prefers the performance and just avoids
all further hardware partitions.

It includes an update of wpa_supplicant to version 2.7.
It includes an update of the OpenSSL baseline to version 1.1.1a.
Update #3472.
Git mirror commit 59f44d20be3f99d181ca742e636d45fc39ec982b.
This commit updates OpenSSL to version 1.1.1. This required an update
of racoon which uses some internal stuff from OpenSSL and seems to be
mostly unmaintained, e.g. there is update in the FreeBSD ports to cope
with OpenSSL 1.1.1.
Update #3472.
The USB_BUS_SPIN_LOCK() is only used internally to the bus driver.
Replace the mutex with an interrupt disable/enable section. Execute the
interrupt filter in a real interrupt context and forward the interrupt
handler to the interrupt server if necessary.
