malloc() and free() should never be used within the OS. This will work in the FLAT build because there is only a single heap, but will cause problems in PROTECTED and KERNEL build modes where there are separate heaps for user and kernel memory.
Typically kmm_malloc(), kmm_zalloc(), and kmm_free() should be called within the kernel in those build modes to use the kernel heap.
Memory is never free. Possible memory leak:
./boards/arm/cxd56xx/common/src/cxd56_crashdump.c: pdump = malloc(sizeof(fullcontext_t));
Memory allocated with malloc(), but freed with kmm_free():
./drivers/usbhost/usbhost_composite.c: cfgbuffer = (FAR uint8_t *)malloc(CUSTOM_CONFIG_BUFSIZE);
Memory is never freed in these cases. It is allocated in the driver initialization logic, but there is no corresponding uninitialization logic; memory is not freed on error conditions:
./arch/arm/src/lc823450/lc823450_i2s.c: priv = (struct lc823450_i2s_s *)zalloc(sizeof(struct lc823450_i2s_s));
./arch/arm/src/sam34/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/sama5/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/samv7/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
Memory is allocated with zalloc() but freed on error conditions with kmm_free():
./arch/arm/src/sama5/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/samv7/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/stm32/stm32_i2s.c: priv = (struct stm32_i2s_s *)zalloc(sizeof(struct stm32_i2s_s));
Memory is never freed:
./drivers/spi/spi_bitbang.c: priv = (FAR struct spi_bitbang_s *)zalloc(sizeof(struct spi_bitbang_s));
arch/arm/src/cxd56xx/cxd56_gnss.c, arch/arm/src/xmc4/xmc4_spi.c,
crypto/blake2s.c, drivers/lcd/pcf8574_lcd_backpack.c, drivers/lcd/st7032.c
User space memory should not be used within the OS and, when it is absolutely necessary to use user-space memory, it should be allocated using kumm_malloc().
clang-check complained like the following.
While this is not a real bug, it's easy to appease.
sim/up_exit.c:68:21: warning: Value stored to 'tcb' during its initialization is never read

ESP32 runs code in a SPI Flash, so users can also use it to store
data directly or mount some parts into a filesystem.
The SPI Flash usually use SPI0.

There are 2 cases affected for this problem:
1) Add source files by config symbol
2) Include header files in #ifdef directive
These 2 cases may not be included in Make.dep and this may prevent the

implement system reset to make nsh reboot work
The QuickFeather board added as an initial target.
These featrues are minimally implemented:
* Clock Configuration -- All clocking registers are defined and
configuration is used to setup the HSO, M4 Core, and M4 Perif
clocks. Additionally some clock debugging is stubbed for
bringing out clock paths to IO pins.
* UART -- The lowputc as well as the serial driver is implemnted
for the single UART device. Currently the configuration is
hard coded, but uses the proper interfaces to later fill in.
* SysTick -- The system tick timer is implemented and clocking
properly. Tickless mode is not yet implemented.
* Interrupts -- The interrupt system is implemented and verified
using the UART and SysTick systems.
* GPIO -- GPIO and IOMUX systems are defined and implemented.
This is verified using the UART as well as the Arch LED
system. The GPIO interupt system is stubbed out but not
implemented.
* Arch LEDS -- The blue LED as part of the RGB LED is configured
and attached to the Arch LED system. This indicates the device
coming online as well as when a hardfault is triggered.
Applications and Testing:
* There is a nsh configuration implemented that includes debug
features as well as the ostest, getprime, and mem test.
All of these have been run and verified.

When any error was detected the buffers descriptors were
blindly initialized. This caused the TX of the MAC to
be in a bad state. The correct thing to do, we disable
the MAC, init the bufffers and re-eanable the MAC.
The interrupts were being throlled at the NVIC. This been
cleaned up.

This fixes the following 3 issues:
1. Wait for send to complete in exchange
Before shutting down the SPI, we have to wait for send to complete; not only
DMA, since DMA just puts data to the SPI fifo. It is not yet out of SPI.
When doing exchange with both send & receive this is not an issue because when
receive dma has completed, it is certain that also the send is.
This can be accomplished by completing the transfer in SPI TXC interrupt
instead of DMA callback.
2. Fix TXDMAEN and RXDMAEN placement
According to the spec, the RXDMAEN must be enabled before
enabling DMA requests for Tx and Rx in DMA registers, and TXDMAEN
after that.
Cleaner place to do this is in spi_dmarxstart and spi_dmatxstart, where
also the dma requests are enabled. This also handles properly the
simplex modes.
3. Remove bus signal glitches when shutting off SPI block
Use AFCNTR to avoid glitches in SPI lines while turning SPI block
on/off during calls to exchange.
