flash: Tidy up coding style for flash functions

2020-05-18T18:53:28+00:00

Some functions use the wrong code style and generate checkpatch errors.
Fix these.

common: Move flash_perror() to flash.h

2020-01-17T18:26:48+00:00

This function belongs more in flash.h than common.h so move it.

Also remove the space before the bracket in some calls.

mtd: rename CONFIG_MTD -> CONFIG_DM_MTD

2019-12-04T04:04:10+00:00

CONFIG_MTD must be reserved for the MTD core. Like any other
subsystem, prefix the symbol by DM when it comes to DM support.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

flash: Fix spelling of "ERR_TIMOUT"

2018-01-29T06:48:59+00:00

checkpatch.pl complains about the spelling of ERR_TIMOUT. Since the
error is only used in a handful of files, we rename the error to
ERR_TIMEOUT.

mtd: cfi: Add support for status register polling

2017-09-26T08:57:53+00:00

The status register is optional in the AMD command sets, but it's
presence can be checked by reading out CFI table entry 0xc bit 0.
If the register is present, prefer using it's bit 7 to determine
if the flash is busy over reading the flash ; this is needed ie.
on Hyperflash memories.

mtd: cfi: Zap cfi_flash_base in DM case

2017-09-26T08:57:53+00:00

Embed the flash base into struct flash_info instead of having ad-hoc
static array in the code. This does not only remove static variable,
but also allows CFI-like controllers, ie. HyperFlash ones, to use most
of the CFI flash code by populating the flash_info with matching base
address.

stm32f1: remove stm32f1 support

2017-08-13T19:17:37+00:00

A few years ago STM32F1 SoCs support has been added :
0144caf22ce6acd5c  gpio: stm32: add stm32f1 support
2d18ef2364fd3561a  ARMv7M: add STM32F1 support

But neither STM32F1 dedicated defconfig nor board was
associated to these commits.

Got confirmation from Tom Rini and Matt Porter to remove
all this code [1]

mtd: cfi: Zap CFI_FLASH_SHIFT_WIDTH redefinition

2017-08-08T12:29:48+00:00

This is defined twice in the same file, with the same value, likely
because of some patch merge issue. Pick the uglier one and nuke it.
