platform: Remove redundant config.mk from all platforms

2022-08-08T04:04:25Z

The options defined in config.mk can be specified in objects.mk of each platform so let us remove config.mk from all platforms. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/fdt: Use kconfig for enabling/disabling

2022-08-08T04:04:08Z

We update FDT support makefile to use kconfig for enabling/disabling. To avoid compilation errors, we also enable FDT for each platform. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

Makefile: Add initial kconfig support for each platform

2022-08-08T04:03:09Z

We extend the top-level makefile to allow kconfig based configuration for each platform where each platform has it's own set of configs with "defconfig" being the default config. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/serial: Initialize platform_uart_data to zero

2022-07-30T06:09:10Z

While it doesn't look like there are any current cases of using uninitialized data, let's zero all the UART data members to be safe. Zero may not actually be better than a random number in some cases, so all structure members should still be validated before use, but at least zero is usually easier to debug than some random stack garbage...

lib: irqchip/plic: Factor out a context init function

2022-06-13T06:24:06Z

This simplifies both the callers and the callees by removing duplicated code and consolidating the error handling. It also fixes two bugs in the process: 1) ie_words was one too large when plic->num_src was a multiple of 32. 2) plic_set_ie takes a 32-bit mask, not a Boolean value, so the FPGA platforms previously only enabled one out of every 32 interrupts.

lib: utils/serial: support 'reg-offset' property

2022-04-17T08:27:48Z

reg-offset property is used for offset to apply to the mapbase from the start of the registers in 8250 UART. In Linux kernel, it has been handled in 8250 UART driver. dt-bindings: /Documentation/devicetree/bindings/serial/8250.yaml Signed-off-by: Zong Li Reviewed-by: Anup Patel
