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.

flash: add device ID for Microchip PIC32 internal flash.

2016-05-20T23:25:50+00:00

Microchip PIC32 has internal parallel flash (non-CFI compliant).
These flash devices do not support any identifier command so no
standard IDs. Added unique IDs to seperate these flash devices
from others supported by U-Boot.

stm32: stm32f4: move flash driver to mtd driver location

2016-03-26T22:49:28+00:00

Same flash driver can be used by other stm32 families like stm32f7.
Better place for this driver would be mtd driver location.

cfi_flash: give default CONFIG_SYS_MAX_FLASH_SECT in flash.h

2015-11-30T12:00:00+00:00

Give default CONFIG_SYS_MAX_FLASH_SECT in flash.h, so that
the header can be included regardless of the present of flash.
The value 512 is the most used.

dm: implement a MTD uclass

2015-11-12T00:26:58+00:00

Implement a Memory Technology Device (MTD) uclass. It should
include most flash drivers in the future. Though no uclass ops
are defined yet, the MTD ops could be used.

The NAND flash driver is based on MTD. The CFI flash and SPI
flash support MTD, too. It should make sense to convert them
to MTD uclass.
