Strongly-Ordered requires aligned access unless
caching is enabled.
Normal memory
Accesses to normal memory region are idempotent...
- unaligned accesses can be supported
With CONFIG_ARMV7M_DCACHE the cache maintenance operation
are not present. Or if CONFIG_ARMV7M_DCACHE_WRITETHROUGH
is on then buffering operations are no-ops.
This change enables MPU_RASR_C and MPU_RASR_B if
CONFIG_ARMV7M_DCACHE is only set.
if CONFIG_ARMV7M_DCACHE_WRITETHROUGH is set then only
MPU_RASR_C is enabled.
N.B When caching is disalbed unaligned access may cause hard faults
so add -mno-unaligned-access
It is always safe to enable Buffering in FLASH to achive unaligned
access leniency, as it is not written to.
This fixes busylooping in work_usrthread, due to incorrect time spec given to sem_timedwait
_SEM_TIMEDWAIT works on absolute time stamps, using CLOCK_REALTIME

A user reported me an issue while following our documentation
then looking his command line error I noticed the openocd stlink
interface was wrong: st-link-v2.cfg -> stlink-v2.cfg
1. Wi-Fi and BLE use common PHY functions.
2. Fix Wi-Fi & BLE coexist adapter error.
3. Update esp-wireless-drivers-3rdparty, provide coexist protection for connection.
1. Fix the issue that Wi-Fi can't connect to some special routers occasionally.
2. Support Wi-Fi 12/13 channel active scanning by default.
3. Update Wi-Fi driver code to fix issue of failure to send pkt.
4. Replace software random with hardware random
5. Fix Wi-Fi mode start error
E51 may configure the L1 and L2 caches. Once configured,
no reconfiguration is possible after hardware reset is
issued.
L2 is 16-way set associative with write-back policy. The
size 2 MB, from which 1 MB is utilized with the values
provided here. That's a total of 8 ways. The rest of the
L2 is left out for the bootloader usage.
mpfs_enable_cache() first checks the bootloader usage
doesn't overlap with the cache itself, thus providing a
set of functional values.

the SDIO clock is not enabled when the bus goes to the idle state, that, in turn, breaks
IRQ delivering mechanism over DAT[1]/IRQ SDIO line to the host.
This reverts commit d9a5b92c1a306a70df52d50a02a80dc8ef20bf0d.
Revert "arch/arm: Remove -march and -mtune"
This reverts commit b8e99cf12f3a287311a2d341f285c71a5da3e4d4.
Bluetooth is not enabled. When Bluetooth is enbaled then it defaults to
64KB. This will not wast those 64KB of memory when Bluetooth is not enabled.
