lib: utils: missing initialization in thead_reset_init

2021-06-11T13:50:16+00:00

If property csr-copy does not exist, fdt_getprop() will return NULL and cnt will have a random value from the stack. Call clone_csrs() only if cnt is initialized to a non-zero value.

lib: utils: consider ':' in stdout-path

2021-06-02T11:36:17+00:00

The value of the /chosen/stdout-path devicetree property is used to determine the UART used by openSBI. According to the devicetree specification the value may contain a hyphen, e.g. chosen { stdout-path = "/serial@f00:115200"; }; If the character ':' is present, it terminates the path of the device.

lib: utils: Try other FDT drivers when we see SBI_ENODEV

2021-05-24T10:19:21+00:00

We should try other FDT drivers when we see SBI_ENODEV returned by cold_init() of FDT driver. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Xiang W

lib: utils/fdt: Replace strcmp with strncmp

2021-05-19T12:05:38+00:00

Use strncmp() instead of strcmp() in __fixup_find_domain_offset() so that it compiles fine when linking with external firmware (such as EDK2). Signed-off-by: Daniel Schaefer Reviewed-by: Xiang W Reviewed-by: Abner Chang Reviewed-by: Anup Patel

lib: utils/fdt: Don't use sbi_string functions

2021-05-19T12:04:06+00:00

When SBI is built by external firmware, we need to use their functions, defined in libfdt_env.h. Just like 2cfd2fc9048806353298a1b967abf985901e36e8 Signed-off-by: Daniel Schaefer Reviewed-by: Abner Chang Reviewed-by: Xiang W Reviewed-by: Anup Patel

we want to use sbi_strncpy as strncpy in the OpenSBI implementation for libfdt. Just like 2845d2d2cf4fb74a89452ba223995aa4a118c07e Signed-off-by: Daniel Schaefer Reviewed-by: Abner Chang Reviewed-by: Xiang W Reviewed-by: Anup Patel

lib: utils/serial: Support Synopsys DesignWare APB UART

2021-05-19T07:33:19+00:00

Synopsys DesignWare APB UART is seen on the StarFive JH7100 SoC. Its programming interface is compatible with the existing 8250 UART driver. Simply add its compatible string to the driver makes it work with the StarFive JH7100 SoC on a BeagleV board. With this patch, the generic platform firmware can be used out of the box on the BeagleV board. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

lib: sbi: Simplify system reset platform operations

2021-04-28T11:55:00+00:00

Instead of having system_reset_check() and system_reset() callbacks in platform operations, it will be much simpler for reset driver to directly register these operations as a device to the sbi_system implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis
