From db5b7f566e513dc1b7f364102010558e5ae7e14f Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 25 Aug 2014 13:34:16 -0300 Subject: net: fec_mxc: Adjust RX DMA alignment for mx6solox mx6solox has a requirement for 64 bytes alignment for RX DMA transfer. Other SoCs work with the standard 32 bytes alignment. Adjust it accordingly by using 64 bytes aligment in the FEC RX DMA buffers, which addresses the needs from mx6solox and also works for the other SoCs.

As explained by Ye Li: "The TDAR bit is cleared when the descriptors are all out from TX ring, but on mx6solox we noticed that the READY bit is still not cleared right after TDAR. These are two distinct signals, and in IC simulation, we found that TDAR always gets cleared prior than the READY bit of last BD becomes cleared. In mx6solox, we use a later version of FEC IP. It looks like that this intrinsic behaviour of TDAR bit has changed in this newer FEC version." Fix this by polling the READY bit of BD after the TDAR polling, which covers the mx6solox case and does not harm the other SoCs. No performance drop has been noticed with this patch applied when testing TFTP transfers on several boards of different i.mx SoCs.

On the Ventana boards the board layout varies little in trace-lengths such that propagation delays are irrelevant thus we can simply things by using calibration values obtained from various board layouts based on a common SoC and DDR chip configuration. This eliminates board-model from being needed allowing more flexibility. These values were tested on a large sample size of Gateworks Ventana boards ranging in layout, and memory configuration over the entire temperature range supported.
