Since dd849ffc, _rodata_start label has been moved to a different linker output section from where the TLS templates (.tdata, .tbss) are located. Since link-time addresses of thread-local variables are calculated relative to the section start address, this resulted in incorrect calculation of THREADPTR/$tp registers. Fix by introducing new linker label, _flash_rodata_start, which points to the .flash.rodata output section where TLS variables are located, and use it when calculating THREADPTR/$tp. Also remove the hardcoded rodata section alignment for Xtensa targets. Alignment of rodata can be affected by the user application, which is the issue dd849ffc was fixing. To accommodate any possible alignment, save it in a linker label (_flash_rodata_align) and then use when calculating THREADPTR. Note that this is not required on RISC-V, since this target doesn't use TPOFF.
ESP32-S3 component
This directory contains support for the upcoming ESP32-S3 SoC. This code is still work in progress and not intended for public use.
