If anyone has any objections, please let me know. ------------------ From: Nicolas Ferre commit 1f591be0a02c697f65a21be35f1d74117bbf4be2 upstream. On some flexcom nodes related to uart, the fifo sizes were wrong: fix them to 32 data. Note that product datasheet is being reviewed to fix inconsistency, but this value is validated by product's designers.
