Use the flag (COP_FLAG_UPDATE)structure member to mark
whether it is just input data.
like this:
can do manys times,just input data
....
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = COP_FLAG_UPDATE;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
can do manys times like frist...
then,the last time
Don't use any flay structure member to mark
this is last time,need get final result
....
cryp.ses = session.ses;
cryp.op = COP_ENCRYPT;
cryp.src = (caddr_t) s;
cryp.len = len;
cryp.flags = 0;
cryp.dst = 0;
cryp.mac = (caddr_t) out;
cryp.iv = 0;
if (ioctl(cryptodev_fd, CIOCCRYPT, &cryp) == -1)
{
warn("CIOCCRYPT");
goto err;
}
....
that will get last result.

There are many small memory block in NuttX system, eg: struct tcb_s,
struct inode, etc, and several disadvantages about them:
1.Their frequent allocate and free cause the system memory fragmentation.
2.Since each memory block has an overhead, the utilization of small memory
blocks is relatively low, which will cause memory waste.
So we can use mempool to alloc smallo block, to improve alloc speed
and utilization, to reduce fragmentation.

do simple copy to instead of memset and memcpy operation because
they have been instrumented, if you access the posion area,
the system will crash.

When invalidate address is not aligned with cache line,
must align address and flush the cache line.

The dual core STM32H747 / STM32H757 there is an additional option to
select SMPS rather than LDO as the power selection.
This commit adds this option to the STM32H747 config and the
stm32h7x7xx source.

The memalign is special to multiple mempool because multiple mempool
doesn't support split and shrink chunk operate. So When you alloc a
memory block and find an aligned address in this block, you need to
occupy 8 bytes before the address to save the address of the padding
size and pool to ensure correct use in realloc and free operations.
So we will use bit1 in the previous address of the address to represent
that it is applied by memalign.

This delta describes the relationship between the block size of each
mempool in multiple mempool by user initialized. It is automatically
detected by the mempool_multiple_init function. If the delta is not
equal to 0, the block size of the pool in the multiple mempool is an
arithmetic progressions, otherwise it is an increasing progressions.

Let's specify size instead of number, so that we can unify the size of

struct stm32_i2c_inst_s instance is allocated on every call to
stm32_i2cbus_initialize, and that instance is supposed to be deleted on every
call to stm32_i2cbus_uninitialize.
The "refs" counter just keeps track on when the last one is deleted, and
everything is unregisterd/disabled.
This reverts commit 8098c80338.
Summary:
- It is applicable to esp32 products and uses the himem part
of 8M psram by creating character devices.
Impact:
- None
Testing:
- Use esp32-wrover series products for more than 1000 functional verifications.
