40be44f827 feat(system): refactor linker scripts
- move .tbss to NOLOAD section
- remove xtensa-specific entities from riscv scripts
- explicit eh_frame terminator instead of "align magic"
- 80 characters line length limit
- refactor comments
- discard .rela sections (the rela data will go to relates sections)

824c8e0593 feat(esp_system): allow .bss to spill over into L2MEM above 0x4ff40000
This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for
esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled:

- LDFLAGS+=--enable-non-contiguous-regions
- ldgen.py replaces "arrays[*]" from sections.ld.in with objects under
  SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo))
- "mapping[*]" - refers to all other data

If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at
least one block of code like this (otherwise it does not make sense):

  .dram0.bss (NOLOAD) :
  {
    arrays[dram0_bss]
    mapping[dram0_bss]
  } > sram_low

  .dram1.bss (NOLOAD) :
  {
    /* do not place here arrays[dram0_bss] because it may be splited
     * between segments */
    mapping[dram0_bss]
  } > sram_high

cb6e2133f0 esp_hw_support: Fix invalid system time if s_esp_rtc_time_us & s_rtc_last_ticks were moved around
The commit fixes the case:
If variables in RTC RAM have been moved around by the linker,
they will be filled with garbage data. Any reset other than OTA would work fine
because the variables would still be initialized from the initial bootup.

So now system time will be valid even after OTA.

The USE_FIXED_STATIC_RAM_SIZE was not actually causing the heap to start
at a fixed address.

2d44dc1eed mmu: driver framework, for vaddr maintenance
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.

This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.

esp_system: allow defining priorities for startup functions
* Some components have initialization dependencies. To account for
  them, simple numeric priority values are introduced.
* esp_system_init_fn_array moved into Flash from DRAM
* System init functions defined using ESP_SYSTEM_INIT_FN now return
  an error code. This enables simpler and more consistent error
  handling in the init functions. Returning an error from an init
  function is now a valid approach — the startup code will print
  an error and abort.

3c9856bdd1 (Xtensa) Build: add .xt.prop and .xt.lit to the compiled ELF file
Adding prop and lit sections to the ELF will let the debugger and the disassembler
have more info about data bytes present in the middle of the Xtensa
instructions, usually used for padding.

69b317368e esp_system: Fix esp32c2/esp32c3/esp32h2 TLS size
The change fixes thread-local-storage size by removing .srodata section
from it. It initially was included in TLS section by mistake.
The issue was found when stack size increased after building applications
with GCC-11.1 compiler. Stack size became bigger because some new data
appeared in .srodata. See more details here:

2fc9bd61bf ulp: refactor ulp component
This commit refactors the ulp component.
Files are now divided based on type of ulp, viz., fsm or risc-v.
Files common to both are maintained in the ulp_common folder.

This commit also adds menuconfig options for ULP within the ulp
component instead of presenting target specific configuations for ulp.

e0d29d4ada esp_system: create ld template to abstract few common settings
PMS aware chips require prefetch padding size for instruction fetch, or
some memory alignment considerations. These settings are now exposed
through kconfig options (hidden) and used through common ld template.
This shall help to add and manage future chips support easily for
these considerations.
