The generic mux clock code for CCF requires reading the clock multiplexer value from HW registers. As sandbox by design has readl() as no-op it was necessary to provide this value in the other way. The new field in the mux structure (accessible only when sandbox is run) has been introduced for this purpose. Signed-off-by: NLukasz Majewski <lukma@denx.de>

If the CLK_GET_RATE_NOCACHE flag is set - the clk_get_parent_rate() provides recalculated clock value without considering the cache setting. This may be necessary for some clocks tightly coupled with power domains (i.e. imx8), and prevents from reading invalid cached values.

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y SHA1: 5752b50477da)to provide clocks support as it is used on the Linux kernel with Common Clock Framework [CCF] setup. The directory structure has been preserved. The ported code only supports reading information from PLL, MUX, Divider, etc and enabling/disabling the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree. One needs to pay attention to the comments indicating necessary for U-Boot's driver model changes. If needed, the code can be extended to support the "set" part of the clock management.

This commit adds the clk_get_by_id() function, which is responsible for getting the udevice with matching clk->id. Such approach allows re-usage of inherit DM list relationship for the same class (UCLASS_CLK). As a result - we don't need any other external list - it is just enough to look for UCLASS_CLK related udevices.

This commit adds the clk_get_parent_rate() function, which is responsible for getting the rate of parent clock. Unfortunately, u-boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in Common Clock Framework [CCF] in Linux. To alleviate this problem - the clk_get_parent_rate() function has been introduced to clk-uclass.c. Signed-off-by: NLukasz Majewski <lukma@denx.de> Reviewed-by: NPeng Fan <peng.fan@nxp.com>

This commit adds the clk_get_parent() function, which is responsible for getting the parent's struct clock pointer. U-Boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in Common Clock Framework [CCF] in Linux. To obtain the pointer to struct clk of parent the pdev->uclass_priv field is read via dev_get_clk_ptr() wrapper.

Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without declaring struct clk. As a result it was only accessible by iterating the udevice's uclass list. This is a problem for clock code, which operates on pointers to struct clk (like clk_get_rate()), not udevices. After this change struct clk is accessible from udevice and udevice from struct clk.

Some storage devices have multiple hw partitions and both address from zero, for example eMMC. However currently block cache invalidation only applies to block write/erase. This can cause a problem that data of current hw partition is cached before switching to another hw partition. And the following read operation of the latter hw partition will get wrong data when reading from the addresses that have been cached previously. To solve this problem, invalidate block cache after a successful select_hwpart operation. Signed-off-by: NWeijie Gao <weijie.gao@mediatek.com>

If U-Boot is loaded and started from TF-A (you need to change SYS_TEXT_BASE to 0x60000000), it will hang up at flash initialization. If secure mode is off (default, or -machine virt,secure=off) at qemu, it will provide dtb with two flash memory banks: flash@0 { bank-width = <0x4>; reg = <0x0 0x0 0x0 0x4000000 0x0 0x4000000 0x0 0x4000000>; compatible = "cfi-flash"; }; If secure mode is on, on the other hand, qemu provides dtb with 1 bank: flash@0 { bank-width = <0x4>; reg = <0x0 0x4000000 0x0 0x4000000>; compatible = "cfi-flash"; }; As a result, flash_init()/flash_get_size() will eventually fail.

Currently, CONFIG_TFABOOT is located in armv8/fsl-layerscape Kconfig, but it will be also useful for other targets if some additional configuration are necessary. So move it to arch/arm/Kconfig. Please note that CONFIG_TFABOOT still depends on CONFIG_ARCH_SUPPORT_TFABOOT and so the menu won't come up if any target doesn't need its own customization for TF-A boot. This will maintain the compatibility.

At the moment mkenvimage has two separate read paths: One to read from a potential pipe, while dynamically increasing the buffer size, and a second one using mmap(2), using the input file's size. This is problematic for two reasons: - The "pipe" path will be chosen if the input filename is missing or "-". Any named, but non-regular file will use the other path, which typically will cause mmap() to fail: $ mkenvimage -s 256 -o out <(echo "foo=bar") - There is no reason to have *two* ways of reading a file, since the "pipe way" will always work, even for regular files. Fix this (and simplify the code on the way) by always using the method of dynamically resizing the buffer. The existing distinction between the two cases will merely be used to use the open() syscall or not. Signed-off-by: NAndre Przywara <andre.przywara@arm.com>

It is perfectly fine for the read(2) syscall to return with less than the requested number of bytes read (short read, see the "RETURN VALUE" section of the man page). This typically happens with slow input (keyboard, network) or with complex pipes. So far mkenvimage expects the exact number of requested bytes to be read, assuming an end-of-file condition otherwise. This wrong behaviour can be easily shown with: $ (echo "foo=bar"; sleep 1; echo "bar=baz") | mkenvimage -s 256 -o out - The second line will be missing from the output. Correct this by checking for any positive, non-zero return value. This fixes a problem with a complex pipe in one of my scripts, where the environment consist of two parts.
