| | | | | | | | | | | | | | | | | | fsl_ddr_set_memctl_regs() is not only used internally in the DDR controller driver, but can also be called by the boards to configure a static setting. Move the prototype to include/ where it can be used by board code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we get a nasty error message if the cpu clock can't be changed: DDRC is clocked by PLL1, can't switch CPU clockinitcall vf610_switch_cpu_clock+0x1/0x198 failed: Invalid argument So let's do the following: - factor out the check from vf610_switch_cpu_clock_to_500mhz() and vf610_switch_cpu_clock_to_400mhz - if clock can't be changed, don't treat it as an error - don't call clock notifier chain if clock can't be changed - add trailing newline to the warning message Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | crypto: add new imx-scc driverSteffen Trumtrar2019-04-127-0/+694
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Security Controller (SCC) is found on (at least) i.MX25 SoCs. It is not a crypto engine in the usual sense. The only supported algorithm in hardware is 3DES and the key is not configurable, but is fused in the hardware. The SCC can be handed some block of data in the red memory space and it will return the encrypted data in the black memory space and vice versa. The API for this driver are the functions - mxc_scc_cbc_des_encrypt - mxc_scc_cbc_des_decrypt Along with this driver a blobgen implementation is provided.

| | | | | | | | | The caam driver needs the variable habv4_need_rng_software_self_test, but this is only declared when HABV4 is enabled.

* clk: socfpga: fix compiler warnings for Cyclone5Ian Abbott2019-04-101-3/+3
| | | | | | | | | | | | | | | When building for Cyclone5 SoCFPGA, the socfpga_a10_pll_init(), socfpga_a10_perith_init() and socfpga_a10_gate_init() functions are defined as dummy functions returning ERR_PTR(-ENOSYS). They are defined with external linkage. With '-Wmissing-prototypes' GCC warns about externally linked function definitions with no preceding prototype. Define them as 'static inline' to avoid the compiler warnings. (Note: Arria10 uses non-dummy versions of these functions declared 'extern' but defined elsewhere.)

| * clk: add ZynqMP clock driverMichael Tretter2019-03-188-0/+1162
| | | | | | | | | | | | | | | | | | | | | | | | The ZynqMP has a platform management unit (PMU) that is responsible for managing the clocks. Therefore, the clock driver uses the firmware driver to control the clocks. The Barebox driver is based on the Linux driver, but contains deviations to make the driver more readable and more consistent.

Drop it. Checking that blockbits is eqal to SECTOR_SHIFT isn't necessary, since that field is filled by the driver and is not changed outsied of it. We know it is going to be SECTOR_SHIFT. Drop it. Checking sector_start > (ulong)-1 doesn't make sense at all since sector start is 'int' and it can't possibly be greater that ULONG_MAX. Drop it. Checking for sector_start >= pblk_dev->blk.num_blocks isn't necessary either, since we shouldn't receive request for invalid read from block layer. Drop it.
