ata: ahci: fix ahci_link_up() type mismatch for LTO

2021-05-24T18:21:30Z

When building highbank_defconfig with LTO, the compiler complains about type mismatch of function ahci_link_up(). The third parameter of this function is of type u8 in drivers/ata/ahci.c, but of type int in board/highbank/ahci.c. There is no reason in using u8, and the code using this function actually passes an int variable into the function (so it is implicitly converted to u8). Change the type of this parameter to int in drivers/ata/ahci.c. Signed-off-by: Marek Behún Reviewed-by: Bin Meng

ARM: fix LTO for apf27

2021-05-24T18:21:30Z

When apf27_defconfig is built with LTO, linking complains about undefined reference to `nand_boot`. This is because it is referenced from inline assembly. Make it visible. Signed-off-by: Marek Behún

treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30Z

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

regmap: fix a serious pointer casting bug

2021-05-24T18:21:30Z

There is a serious bug in regmap_read() and regmap_write() functions where an uint pointer is cast to (void *) which is then cast to (u8 *), (u16 *), (u32 *) or (u64 *), depending on register width of the map. For example given a regmap with 16-bit register width the code int val = 0x12340000; regmap_read(map, 0, &val); only changes the lower 16 bits of val on little-endian machines. The upper 16 bits will remain 0x1234. Nobody noticed this probably because this bug can be triggered with regmap_write() only on big-endian architectures (which are not used by many people anymore), and on little endian this bug has consequences only if register width is 8 or 16 bits and also the memory place to which regmap_read() should store it's result has non-zero upper bits, which it seems doesn't happen anywhere in U-Boot normally. CI managed to trigger this bug in unit test of dm_test_devm_regmap_field when compiled for sandbox_defconfig using LTO. Fix this by utilizing an union { u8; u16; u32; u64; } and reading data into this union / writing data from this union.

- Various clk/pinctrl updates to re-sync with Linux and other fixes

pinctrl: renesas: Implement unlock register masks

2021-05-21T13:00:17Z

The V3U SoC has several unlock registers, one per register group. They reside at offset zero in each 0x200 bytes-sized block. To avoid adding yet another table to the PFC implementation, this patch adds the option to specify an address mask instead of the fixed address in sh_pfc_soc_info::unlock_reg. This is a direct port of Linux 5.12 commit e127ef2ed0a6 ("pinctrl: renesas: Implement unlock register masks") by Ulrich Hecht Signed-off-by: Marek Vasut

pinctrl: renesas: Fix R-Car Gen2 help text

2021-05-21T13:00:17Z

The help text for Gen2 entries had a copy paste error, still containing the Gen3 string, while the description was correctly listing Gen2. Fix the help text. Signed-off-by: Marek Vasut

pinctrl: renesas: Deduplicate Kconfig

2021-05-21T13:00:17Z

The help text in the Kconfig file was always a copy of the same thing. Move single copy into the common PFC driver entry instead. Also fix a copy-paste error in the PFC help text, which identified PFC as clock. Signed-off-by: Marek Vasut

gpio: renesas: Pass struct udevice to rcar_gpio_set_direction()

2021-05-21T13:00:17Z

Pass struct udevice to rcar_gpio_set_direction() in preparation of quirk handling in rcar_gpio_set_direction(). No functional change. Signed-off-by: Marek Vasut

clk: renesas: Deduplicate gen3_clk_get_rate64() PLL handling

2021-05-21T13:00:17Z

Most of the PLLx, MAIN, FIXED clock handlers are calling very similar code, which determines parent rate and then applies multiplication and division. The only difference is whether multiplication is fixed factor or coming from CRx register. Deduplicate the code into a single function. Signed-off-by: Marek Vasut
