Subject: [PATCH 14/87] ARM: OMAP2+: GPMC: fix device size setup
|
|
|
|
commit 8ef5d844cc3a644ea6f7665932a4307e9fad01fa upstream.
|
|
|
|
following statement can only change device size from 8-bit(0) to 16-bit(1),
|
|
but not vice versa:
|
|
|
|
regval |= GPMC_CONFIG1_DEVICESIZE(wval);
|
|
|
|
so as this field has 1 reserved bit, that could be used in future,
|
|
just clear both bits and then OR with the desired value
|
