* mtd: cfi: respect reg address lengthNuno Sá2023-05-151-0/+1
| | | | | | | | | | | flash_get_size() will get the flash size from the device itself and go through all erase regions to read protection status. However, the device mappable region (eg: devicetree reg property) might be lower than the device full size which means that the above cycle will result in a data bus exception. This change fixes it by reading the 'addr_size' during probe() and also use that as one possible upper limit. Signed-off-by: Nuno Sá <nuno.sa@analog.com>
* Audit <flash.h> inclusionTom Rini2022-08-041-4/+1
| | | | | | | | | | | | A large number of files include <flash.h> as it used to be how various SPI flash related functions were found, or for other reasons entirely. In order to migrate some further CONFIG symbols to Kconfig we need to not include flash.h in cases where we don't have a NOR flash of some sort enabled. Furthermore, in cases where we are in common code and it doesn't make sense to try and further refactor the code itself in to new files we need to guard this inclusion.

* cfi_flash: Fix detection of 8-bit bus flash devices via address shiftJagannadha Sutradharudu Teki2021-04-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had a problem detecting 8/16bit flash devices connected only via 8bits to the SoC for quite a while. Commit 239cb9d9 [mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally fixed this 8-bit bus support. But also broke some other boards using this cfi driver. So this patch had to be reverted. I spotted a different, simpler approach for this 8-bit bus support on the barebox mailing list posted by Oleksij Rempel <bug-track@fisher-privat.net>: http://www.spinics.net/lists/u-boot-v2/msg14687.html Here the commit text: " Many cfi chips support 16 and 8 bit modes. Most important difference is use of so called "Q15/A-1" pin. In 16bit mode this pin is used for data IO. In 8bit mode, it is an address input which add one more least significant bit (LSB). In this case we should shift all adresses by one: For example 0xaa << 1 = 0x154 " This patch now is a port of this barebox patch to U-Boot. Along with the change w.r.t from barebox, Some flash chips can support multiple bus widths, override the interface width and limit it to the port width. Tested on 16-bit Spansion flash on sequoia. Tested 8-bit flashes like 256M29EW, 512M29EW.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Tom Rini <trini@konsulko.com>

* mtd/cfi: add support for SST 4KB sector granularityAngelo Dureghello2013-01-101-0/+1
| | | | | | | | | | | | | | | | | | | Add support for SST 4KB sector granularity. Many recent SST flashes, i.e. SST39VF3201B and similar of this family are declared CFI-conformant from SST. They support CFI query, but implement 2 different sector sizes in the same memory: a 64KB sector (they call it "block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector", erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh of cfi query struct, detects a number of secotrs for the 4KB granularity (flinfo shows it). For all other aspects, they are CFI compliant, so, as Linux do, i think it's a good idea to handle these chips in the CFI driver, with a fixup to allow 4KB granularity, as should be expected, instead of 64KB.

By moving these optional variables and defines into the common code, board specific code is minimized.

* flash/cfi_flash: Use virtual sector start address, not physBecky Bruce2009-02-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | include/flash.h was commented to say that the address in flash_info->start was a physical address. However, from u-boot's point of view, and looking at most flash code, it makes more sense for this to be a virtual address. So I corrected the comment to indicate that this was a virtual address. The only flash driver that was actually treating the address as physical was the mtd/cfi_flash driver. However, this code was using it inconsistently as it actually directly dereferenced the "start" element, while it used map_physmem to get a virtual address in other places. I changed this driver so that the code which initializes the info->start field calls map_physmem to get a virtual address, eliminating the need for further map_physmem calls. The code is now consistent. The *only* place a physical address should be used is when defining the flash banks list that is used to initialize the flash_info struct, usually found in the board config file.
