* 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
Closes IDF-3391
Updates the following with changes from verification branches:
* esp_rom linker files
* rtc_cntl and system reg and struct headers
Also updates:
* GDMA driver with new register layout
* esptool submodule commit
Additionally, always enable the partition MD5 check if flash encryption is on in
Release mode. This ensures the partition table ciphertext has not been modified
(CVE-2021-27926).
The exception is pre-V3.1 ESP-IDF bootloaders and partition tables, which
don't have support for the MD5 entry.
* Patched longjmp to be context-switch safe
longjmp modifies the windowbase and windowstart
registers, which isn't safe if a context switch
occurs during the modification. After a context
switch, windowstart and windowbase will be
different, leading to a wrongly set windowstart
bit due to longjmp writing it based on the
windowbase before the context switch. This
corrupts the registers at the next window
overflow reaching that wrongly set bit.
The solution is to disable interrupts during
this code. It is only 6 instructions long,
the impact shouldn't be significant.
The fix is implemented as a wrapper which
replaces the original first instructions of
longjmp which are buggy. Then, it jumps back
to execute the rest of the original longjmp
function.
Added a comparably reliable test to the
test apps.
