drivers/mtd/s25fl1.c: During a MTDIOC_GEOMETRY ioctl call, the driver was incorrectly reporting the blocksize to be the same as the erasesize. The blocksize should be 256 (the page size). This patch fixes that, and now the SmartFS configration is working.

Corrections for the i.MXRT Ethernet:
...
(1) Now the Ethernet is completely re-initialized when an error occurs by means of taking the interface down and back up but the PHY is _not_ renegotiated for that case because that is very time consuming and an error in the Ethernet is no reflection on the state of the PHY anyway.
(2) Explicitly sets the expected PHY address to zero (this could be moved into the config) rather than searching for it which takes ages, and it's zero anyway for this board (that's the broadcast address, and anything that cannot respond on that has multiple PHYs, so that would be a new board).
(3) Allows for the renegotiation of the PHY to be optional when a reset is needed. If a non-renegotiated reset doesn't result in good comms to the PHY then it'll automatically be escalated to a renegotiated one.
(4) Only performs a reset for errors that need it (the CRITICAL_ERROR define). The list of errors that need reset are somewhat arbitrarily chosen based on my prejudices and might need to be revisited, but certainly the jabber errors don't need reset, the partial packet is thrown away by the layer above anyway.
(5) Re-loads the multicast table on reset.
(6) Adds a bit more logging into the imxrt Ethernet module.

Pull request for mtd/progmem refactoring.
* mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks
page is a unit for read/write operation.
eraseblock is a unit for erase operation.
up_progmem_npages is a little bit confusing because it returns number of

There was a reference counting problem in the TPC logic of net_clone(). net_clone() which is the common logic underlying dup() and dup2() for sockets. When net_clone() calls net_start_monitor() and net_start_monitor() returns a failure (because the underlying TCP connection) then net_clone() must back out the reference count on the structure. Problem noted by Pascal Speck and this implementation of the solution is based on his suggestion.

...
This commit backs out most of commit b4747286b1
. That change was added because sem_wait() would sometimes cause cancellation points inappropriated. But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.
In the OS, all calls to sem_wait() changed to nxsem_wait(). nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.
In all OS functions (not libraries), change sem_wait() to nxsem_wait(). This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.
sched/semaphore: Add the function nxsem_wait(). This is a new internal OS interface. It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

MTD M2PX: If we READ while a write/erase is pending, the command is ignored and the write/erase continues. If we dont catch this situation we will return garbage to the user because the flash will not execute the command.

alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well).
...
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.

Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver.
...
BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.
I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!

Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors
