The rom function on the s2 and s3 only counts one page for any pages
which are mapped to page 0 of flash as the Cache_Flash_To_SPIRAM_Copy
function attempts to map all flash page 0 mapped pages to one PSRAM
page.
As this function can be called for multiple regions, it needs to track
if a page mapped to page 0 has previously been accounted for by a
previous call. It does this using the page0_mapped in-out parameter.
This logic contains an error:
```
if (*page0_mapped == 0) {
// BUG: If page0_count is 0, 1 is still added
count = valid_flash_count + 1 - page0_count;
} else {
count = valid_flash_count - page0_count;
}
*page0_mapped += page0_count;
return count;
```
The current Cache_Count_Flash_Pages wrapper in the idf attempts to
compensate for this bug by checking if the page0_mapped parameter was
changed by a call to the function and reducing the count if it has not.
This, however, will incorrectly over-compensate in situations where the
initial value of page0_mapped was not zero as the code above only
miscounts when it was zero.
This patch addresses the issue in this wrapper function by correctly
compensating for the bug only in cases where the final page0_mapped
value is 0.
The original ROM function enabled output for the pad first, and then connected the signal
This could result in an undesired level change at the pad

The integrity_walker now calls the integrity check hook to control
free AND used blocks of memory in the TLSF pool. This integrity walker
function is called from tlsf_check_pool.
This commit creates a patch of integrity_walker function to update the
outdated implementation in the ROM.
- Support SOC ROOT clock source switch
- Support CPU frequency change
- Support RTC SLOW clock source switch
- Support RTC SLOW clock + RC FAST calibration
Remove FPGA build for esp32h2
The tlsf implementation in the ROM does not provide a mechanism
to register a callback to be called in by tlsf_check().
This commit is creating a patch of the tlsf implementation to provide
a definition of the function allowing to register the callback called
in tlsf_check() and add the call of this callback in tlsf_check().
This patch is only compiled for target(s) with ESP_ROM_HAS_HEAP_TLSF
set and ESP_ROM_TLSF_CHECK_PATCH set. For all the other configurations
the environment remains unchanged by those modifications.
* On S3, the placement of ROM functions is
ECO-dependent. Hence, we don't jump into
the middle of the longjmp function in ROM
on S3 anymore.
Instead, the whole longjump function is used
in the patch.
* Also properly excluded the patch from
bootloader build with Makefiles
