The implicit promise of heap_alloc_caps() and friends is that the memory it
returns is fit for the purpose as requested in the caps field. Before
this commit, that did not happen; e.g. DMA-capable memory wass returned
from a correct region, but not aligned/sized to something the DMA subsystem
can handle.
This commit adds an API to the esp_mm component that is then used by the
heap component to adjust allocation alignment, caps and size dependent on
the hardware requirement of the requested allocation caps.
Many places in the ESP_SYSTEM are using CONFIG_FREERTOS_UNICORE instead of CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE (GitHub PR)

* All components which won't build (yet) on Linux are excluded.
This enables switching to Linux in an application without
explicitly setting COMPONENTS to main in the main
CMakeLists.txt.
* ESP Timer provides headers for Linux now
* automatically disabling LWIP in Kconfig if it is not available
doc(linux): brought section
"Component Linux/Mock Support Overview" up to date
Some component test apps do not use the "set(COMPONENTS main)" command in their
project level "CMakeLists.txt", thus leading to their builds pulling in all
ESP-IDF components.
This commit trims the build of multiple component test apps:
- Add "set(COMPONENTS main ...)" to project level "CMakeLists.txt"
- Add missing "PRIV_REQUIRES" in some "main" component "CMakeLists.txt"
Also removed repeated configuraiton options in legacy_i2c_driver/sdkconfig.ci.defaults
as they are already specified in legacy_i2c_driver/sdkconfig.defaults
ESP_CACHE_MSYNC_FLAG_DIR_C2M: From cache to memory
ESP_CACHE_MSYNC_FLAG_DIR_M2C: From memory to cache
By default, if no direction flag is set, it will fallback C2M direction.
For M2C direction, now this API will do an invalidation.
- MMU configuration related kconfig options will be in soc, or
esp_hw_support
- Cache configuration related kconfig options will be in soc, or
esp_hw_support
- mmap driver and msync driver kconfig options will be still in esp_mm.
As there's no kconfig options for them yet, removed kconfig files
Prior to this commit, we don't consider the offset of the irom vaddr
start.
If the offset + size is bigger than the MMU page size, for example:
MMU page size: 0x10000
irom vaddr: 0x4200_0800, so offset = 0x800
irom size: 0xF900
offset + size = 0x10100
Under this condition, the 0x4200_0000 ~ 0x4202_0000, two MMU pages are
used.
With this commit, when reserving the irom and drom, we take the offset
into consideration as well.
