| * treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()Masahiro Yamada2020-07-2046-47/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work. I generated this commit by the following command: $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \ xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/' I manually fixed drivers/usb/host/ehci-mx6.c Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Some of the Micron SPI NAND devices have the "Continuous Read" feature enabled by default, which does not fit the subsystem needs. In this mode, the READ CACHE command doesn't require the starting column address. The device always output the data starting from the first column of the cache register, and once the end of the cache register reached, the data output continues through the next page. With the continuous read mode, it is possible to read out the entire block using a single READ command, and once the end of the block reached, the output pins become High-Z state. However, during this mode the read command doesn't output the OOB area. Hence, we disable the feature at probe time.

| | | | | | | | | | | | | | | | | The types of "offset" and "size" of "struct mtd_partition" are uint64_t, while mtd_parse_partitions() uses int to work with these values. When the offset reaches 2GB, it is interpreted as a negative value, which leads to error messages like mtd: partition "<partition name>" is out of reach -- disabled eg. when using the "ubi part" command. Fix this by using uint64_t for cur_off and cur_sz.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.
