2019-04-26arm: lpc32xx: Fix timer initializationGregory CLEMENT
The match controller register is not cleared during initialization. However, some bits of this register may reset the TC if tnMRx match it. As we can't make any assumption about how U-Boot is launched by the first stage bootloader (such as S1L) clearing this register ensure that the timers work as expected.

2018-10-19arm: lpc32xx: add CONFIG_ARCH_LPC32XX build optionVladimir Zapolskiy

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2017-01-20serial, ns16550: bugfix: ns16550 fifo not enabledHeiko Schocher
commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor" breaks u-boot commandline working with long commands sending to the board. Since the above patch, you have to setup the fcr register. For board/archs which enable OF_PLATDATA, the new field fcr in struct ns16550_platdata is not filled with a default value ... This leads in not setting up the uarts fifo, which ends in problems, when you send long commands to u-boots commandline. Detected this issue with automated tbot tests on am335x based shc board. The error does not popup, if you type commands. You need to copy&paste a long command to u-boots commandshell (or send a long command with tbot) Possible boards/plattforms with problems: ./arch/arm/cpu/arm926ejs/lpc32xx/devices.c ./arch/arm/mach-tegra/board.c ./board/overo/overo.c ./board/quipos/cairo/cairo.c ./board/logicpd/omap3som/omap3logic.c ./board/logicpd/zoom1/zoom1.c ./board/timll/devkit8000/devkit8000.c ./board/lg/sniper/sniper.c ./board/ti/beagle/beagle.c ./drivers/serial/serial_rockchip.c Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Tested-by: Adam Ford <aford173@gmail.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-03-14ARM: Various: Future-proof serial platdataAdam Ford
A few boards still use ns16550_platdata structures, but assume the structure is going to be in a specific order. By explicitly naming each entry, this should also help 'future-proof' in the event the structure changes. Tested on the Logic PD Torpedo + Wireless. I only changed a handful of devices that used the same syntax as the Logic board. Appologies if I missed one or stepped on toes. Thanks to Derald Woods and Alexander Graf.

It was reverted out, and and if it did exist, it would get initialized to 0 by default. V2: I hastily copy-pasted the boards without looking at the UART number.

2016-01-13arm: lpc32xx: switch SPL builds to driver modelVladimir Zapolskiy
For NXP LPC32xx boards the change enables SPL_DM option, this allows to use any driver model UART driver in SPL images, hence a restriction on HSUART in SPL image is removed and well as definitions for non-DM NS16550 driver, its DM version is used instead. Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE for LPC32xx boards. The change adds about 5KB to the resulting SPL image (for devkit3250 board SPL image is increased from 10672 to 15608 bytes).

2016-01-13arm: lpc32xx: switch serial console to driver modelVladimir Zapolskiy
On NXP LPC32xx platform for non-SPL builds the change adds standard (NS16550) and high-speed UARTs to driver model. Due to specific of DM NS16550 device description UART clock can not be got in runtime and by default it is set to 13MHz, if board PERIPH_CLK is different, this should be specified in board configuration file. For SPL builds HSUARTs are disabled and non-DM NS16550 driver is compiled, if needed. The change also updates default configs of devkit3250 and work_92105 boards to reflect updates in platform files.

2015-10-11lpc32xx: fix calculation of HCLK PLL output clockVladimir Zapolskiy
Execution branches on feedback mode are swapped, this has no effect if default direct mode is on (then p_div is equal to 1 and Fout equals to Fcco), that's why the problem remained unnoticed for a long time. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com>
2015-09-11lpc32xx: remove duplicated DMA_CLK_ENABLE bit definitionVladimir Zapolskiy
Because there is an originally defined CLK_DMA_ENABLE macro in clk.h, no reason to add another DMA_CLK_ENABLE macro with the same value. Remove DMA_CLK_ENABLE, since it does not follow naming convention from the code, this implies renaming of DMA_CLK_ENABLE to CLK_DMA_ENABLE in lpc32xx/devices.c file.

2015-08-12nand: lpc32xx: add SLC NAND controller supportVladimir Zapolskiy
The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

2015-08-11net: lpc32xx: add RMII phy mode supportVladimir Zapolskiy
LPC32xx MAC and clock control configuration requires some minor quirks to deal with a phy connected by RMII. It's worth to mention that the kernel and legacy BSP from NXP sets SUPP_RESET_RMII == (1 << 11) bit, however the description of this bit is missing in shared LPC32x0 User Manual UM10326 Rev. 3, July 22, 2011 and in LPC32x0 Draft User Mannual Rev. 00.27, November 20, 2008, also in my tests an SMSC LAN8700 phy device connected over RMII seems to work correctly without touching this bit. Add support of RMII, if CONFIG_RMII is defined, this option is aligned with a number of boards, which already define the same config value.
