From a077ac13d03c8cde646ddab30b03ec0f8b753e1e Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Wed, 2 Aug 2023 11:09:43 -0400 Subject: Kconfigs: Correct default of "0" on hex type entries It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

Add new optional callback which can be used at driver level to indicate whether a buffer alignment is suitable for the device DMA or not, and trigger use of generic bounce buffer implementation to help use of unsuitable buffers at the expense of performance degradation.
