* driver/ddr/fsl: Revise workaround A008511 for A009803York Sun2016-09-14-36/+47
| | | | | | | | | | | | | | | DDR controller 5.2.1 has this erratum A008511 partially fixed. The workaround needs to be adjusted to take advantage of Vref training. This patch enables the training and force output enable to be off. Erratum A009803 requires the controller to be idel before enabling address parity. It was combined with workaround for A008511. With new A008511 flow, this flow needs to be changed to enabling data init (D_INIT) after the address parity is enabled.

* | arm: mvebu: a38x: Weed out floating point useMarek Vasut2016-05-20-19/+10
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For reason unknown, recently, the DDR init code writers are really fond of hiding some small floating point operating deep in their creations. This patch removes one from the Marvell A38x code. Instead of returning size of chip as float from ddr3_get_device_size() in GiB units, return it as int in MiB units. Since this would interfere with the huge switch code in ddr3_calc_mem_cs_size(), rework the code to match the change. Before this patch, the cs_mem_size variable could have these values: ( { 16, 32 } x { 8, 16 } x { 0.01, 0.5, 1, 2, 4, 8 } ) / 8 = { 0.000000, 0.001250, 0.002500, 0.005000, 0.062500, 0.125000, 0.250000, 0.500000, 1.000000, 2.000000, 4.000000, } The switch code checked for a subset of the resulting RAM sizes, which is in range 128 MiB ... 2048 MiB. With this patch, the cs_mem_size variable can have these values: ( { 16, 32 } x { 8, 16 } x { 0, 512, 1024, 2048, 4096, 8192 } ) / 8 = { 0, 64, 128, 256, 512, 1024, 2048, 4096 } To retain previous behavior, filter out 0 MiB (invalid size), 64 MiB and 4096 MiB options.
