* Initial pass of EdgeCore platform changes. * Remove libevent dependency from lldpd. * Remove python2 dependencies python3.7 force from platform install script. * Include usbmount support changes. * Add missing 4630 install file. * Update a few file permissions. Add umask line to Makefile. Specify python3.9 in install script. * Misc platform updates: - Add missing fan drawer component to sonic_platform - Remove kernel version specification from Makefile - Update to 4630 utility * - Fix file permissions on source files - Fix compile issue with 4630 driver modules (set_fs, get_fs, no longer supported in kernel 5.10) * Fix missing/extra parens in 4630 util script. * Fix indentation in fanutil.py. * Integrate deltas from Edgecore to ec_platform branch. * Installer update from Edgecore to resolve smbus serial console errors. * Update stable_size for warm boot. * Fix SFP dictionary key to match xcvrd. * - Add missing define in event.py files needed for xcvrd - Fix SFP info dict key for 7xxx switches * 5835 platform file updates including installer and 5835 utility. * 5835 fix for DMAR errors on serial console. * Don't skip starting thermalctld in the pmon container. * Revert several changes that were not related to platform. * Run thermalctld in pmon container. * Don't disable thermalctld in the pmon container. * Fix prints/parens in 7816 install utility. * - Incorporate 7816 changes from Edgecore - Fix 7326 driver file using old kernel function * Update kernel modules to use kernel_read(). * Fix compile errors with 7816 and 7326 driver modules. * Fix some indents preventing platform files from loading. * Update 7816 platform sfp dictionary to match field names in xcvrd. * Add missing service and util files for 7816. * Update file names, etc. based on full SKU for 7816. * Delete pddf files not needed. These were causing conflicts with API2.0 implementation. * Remove pddf files suggested by Edgecore that were preventing API2.0 support from starting. * Install API2.0 file instead of pddf. * Update 7326 mac service file to not use pddf. Fix syntax errors in 7326 utility script. * Fix sonic_platform setup file for 7326. * Fix syntax errors in python scripts. * Updates to 7326 platform files. * Fix some tab errors pulled down from master merge. * Remove pddf files that were added from previous merge. * Updates for 5835. * Fix missing command byte for 5835 psu status. * Fix permission bits on 4630 service files. * Update platforms to use new SFP refactoring. * Fix unused var warnings.
