2019-12-02Move strtomhz() to vsprintf.hSimon Glass1-0/+1
At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2019-02-27cpu: Bind timer driver for boot hartAtish Patra1-3/+4
Currently, timer driver is bound only for hart0. There is no mandatory requirement that hart0 should always come up. In fact, HiFive Unleashed SoC hart0 doesn't boot in S-mode because it only has M-mode. The timer driver should be bound for boot hart.

2018-07-11cpu: bmips: fix probe to get the addressPhilippe Reynes1-1/+1
In the device tree, the address for cpu is located in the node "cpus", not in the cpu node (for exemple cpu@0). So when probing cpu, the cpu address must be read in the cpu parent. The commit "cpu: bmips: convert to use live dt" (sha1: c444afbbefa103d567f197393d39ec0fcca21a0c) change this behaviour and read the address in the cpu node when probing cpu. We fix this by reading the address in the cpu parent. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2-4/+2
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

Most of the MP initialization codes in arch/x86/cpu/baytrail/cpu.c is common to all x86 processors, except detect_num_cpus() which varies from cpu to cpu.
