From be3f06bcc47e04bfc5fb7c900958918e2d019ef4 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 12 Jun 2015 14:52:20 +0800 Subject: x86: dm: Clean up cpu drivers This commit does the following to clean up x86 cpu dm drivers: - Move cpu_x86 driver codes from arch/x86/cpu/cpu.c to a dedicated file arch/x86/cpu/cpu_x86.c - Rename x86_cpu_get_desc() to cpu_x86_get_desc() to keep consistent naming with other dm drivers - Add a new cpu_x86_bind() in the cpu_x86 driver which does exactly the same as the one in the intel baytrail cpu driver - Update intel baytrail cpu driver to use cpu_x86_get_desc() and cpu_x86_bind() Signed-off-by: Bin Meng Acked-by: Simon Glass --- arch/x86/cpu/cpu_x86.c | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 arch/x86/cpu/cpu_x86.c (limited to 'arch/x86/cpu/cpu_x86.c') diff --git a/arch/x86/cpu/cpu_x86.c b/arch/x86/cpu/cpu_x86.c new file mode 100644 index 0000000000..d32ba6614e --- /dev/null +++ b/arch/x86/cpu/cpu_x86.c @@ -0,0 +1,48 @@ +/* + * Copyright (C) 2015, Bin Meng + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include +#include +#include +#include +#include + +int cpu_x86_bind(struct udevice *dev) +{ + struct cpu_platdata *plat = dev_get_parent_platdata(dev); + + plat->cpu_id = fdtdec_get_int(gd->fdt_blob, dev->of_offset, + "intel,apic-id", -1); + + return 0; +} + +int cpu_x86_get_desc(struct udevice *dev, char *buf, int size) +{ + if (size < CPU_MAX_NAME_LEN) + return -ENOSPC; + + cpu_get_name(buf); + + return 0; +} + +static const struct cpu_ops cpu_x86_ops = { + .get_desc = cpu_x86_get_desc, +}; + +static const struct udevice_id cpu_x86_ids[] = { + { .compatible = "cpu-x86" }, + { } +}; + +U_BOOT_DRIVER(cpu_x86_drv) = { + .name = "cpu_x86", + .id = UCLASS_CPU, + .of_match = cpu_x86_ids, + .bind = cpu_x86_bind, + .ops = &cpu_x86_ops, +}; -- cgit
