[PATCH] serial: mxc: Wait until TX FIFO is not full
by Fabio Estevam 26 Oct '22

26 Oct '22

From: Fabio Estevam <festevam(a)denx.de> Tim Harvey reported the console garbage on imx6 since commit c7878a0483c5 ("serial: mxc: have putc use the TXFIFO"). Do as suggested by Pali Rohár where the the driver should not return -EAGAIN when the TX FIFO is full. It should keep waiting until the TX FIFO is no longer full. This also aligns with the implementation of the imx serial driver in the kernel: static void imx_uart_console_putchar(struct uart_port *port, unsigned char ch) { struct imx_port *sport = (struct imx_port *)port; while (imx_uart_readl(sport, imx_uart_uts_reg(sport)) & UTS_TXFULL) barrier(); imx_uart_writel(sport, ch, URTX0); } Fixes: c7878a0483c5 ("serial: mxc: have putc use the TXFIFO") Reported-by: Tim Harvey <tharvey(a)gateworks.com> Suggested-by: Pali Rohár <pali(a)kernel.org> Signed-off-by: Fabio Estevam <festevam(a)denx.de> --- drivers/serial/serial_mxc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/serial/serial_mxc.c b/drivers/serial/serial_mxc.c index 4cf79c1ca24f..332219fa87fc 100644 --- a/drivers/serial/serial_mxc.c +++ b/drivers/serial/serial_mxc.c @@ -311,8 +311,8 @@ static int mxc_serial_putc(struct udevice *dev, const char ch) struct mxc_serial_plat *plat = dev_get_plat(dev); struct mxc_uart *const uart = plat->reg; - if (readl(&uart->ts) & UTS_TXFULL) - return -EAGAIN; + while (readl(&uart->ts) & UTS_TXFULL) + barrier(); writel(ch, &uart->txd); -- 2.25.1

[u-boot][PATCH v2 0/4] Introduce MEMORY uclass and TI GPMC driver
by Roger Quadros 26 Oct '22

26 Oct '22

Hi, This series introduces the MEMORY controller uclass for the drivers that exist in drivers/memory directory. With that, we add the TI GPMC Memory controller driver as the first user of this uclass. The GPMC is a unified memory controller dedicated for interfacing with external memory devices like - Asynchronous SRAM-like memories and ASICs - Asynchronous, synchronous, and page mode burst NOR flash - NAND flash - Pseudo-SRAM devices The driver is pulled straight from the Linux kernel and adapted for u-boot. This driver will take care of setting up the GPMC based on the settings specified in the Device tree and then probe its children.

[u-boot][PATCH] spl: spl_legacy: Fix NAND boot on OMAP3 BeagleBoard
by Roger Quadros 26 Oct '22

26 Oct '22

OMAP3 BeagleBoard NAND boot hangs when spl_load_legacy_img() tries to read the header into 'struct hdr' which is allocated on the stack. As the header has already been read once before by spl_nand.c, we can avoid the extra header read here by simply passing around the pointer to the header. This fixes NAND boot on OMAP3 BeagleBoard.

[PATCH v2] serial: mxc: Keep the original FIFO empty check
by Fabio Estevam 26 Oct '22

26 Oct '22

From: Fabio Estevam <festevam(a)denx.de> Tim Harvey reported that since commit c7878a0483c5 ("serial: mxc: have putc use the TXFIFO"), console messages put inside board_init() are no longer printed correctly. This change added a check to handle the UART FIFO full condition and removed the UART FIFO empty check, which causes the problem. To avoid console corruption, add back the original UART FIFO empty check so that when the FIFO is empty, mxc_serial_putc() returns -EAGAIN to the core serial-uclass.c. This way the serial core can properly handle the UART empty condition by not doing character transmission when -EAGAIN is returned.
