Merge patch series "nand: Add sandbox tests"
To quote the author:
This series tests raw nand flash in sandbox and fixes various bugs discovered in
the process. I've tried to do things in a contemporary manner, avoiding the
(numerous) variations present on only a few boards. The test is pretty minimal.
Future work could test the rest of the nand API as well as the MTD API.
Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost
everything grows by a few bytes due to nand_page_size. A few boards grow more,
mostly those using nand_spl_loaders.c. CI at [2].

+Sandbox NAND
+============
+
+The sandbox NAND controller emulates a NAND controller and attached devices.
+
+Required properties:
+- compatible: "sandbox,nand"
+- #address-cells: Must be 1
+- #size-cells: Must be 0
+
+Any number of child nodes may be present, each representing a NAND device:
+
+Required Properties:
+- reg: The chip-select(s) to use. Only single-die devices are supported for now.
+- sandbox,id: An array of bytes to be reported by the READID (0x90) command
+- sandbox,erasesize: The block size (erase size) of the device, in bytes. Must
+ be a power-of-two multiple of the page size.
+- sandbox,oobsize: The size of the OOB area per page, in bytes.
+- sandbox,pagesize: The page size (write size) of the device, in bytes. Must be
+ a power of two.
+- sandbox,pages: The total number of pages in the device.
+- sandbox,err-count: Number of bit errors to inject per step.
+- sandbox,err-step-size: Size of the step to use when injecting errors, in
+ bytes. Must evenly divide the page size.
+
+Optional properties:
+- sandbox,onfi: The complete ONFI parameter page, including the CRC. Should be
+ exactly 256 bytes.
+- Any common NAND chip properties as documented by Linux's
+ Documentation/devicetree/bindings/mtd/raw-nand-chip.yaml
+
+To match U-Boot's error correction capabilities, errors are only injected into
+the data area and the ECC codes. Other data in the OOB area is never corrupted.
+Generally, sandbox,err-step-size should be the same as the ECC step size, and
+sandbox,err-count should be less than the number of correctable bit errors (the
+ECC strength).
+
+Example
+-------
+
+nand-controller {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "sandbox,nand";
+
+ nand@0 {
+ reg = <0>;
+ nand-ecc-mode = "soft";
+ sandbox,id = [00 e3];
+ sandbox,erasesize = <(8 * 1024)>;
+ sandbox,oobsize = <16>;
+ sandbox,pagesize = <512>;
+ sandbox,pages = <0x2000>;
+ sandbox,err-count = <1>;
+ sandbox,err-step-size = <512>;
+ };
+};
