[U-Boot] [PATCH v2] gpio: spear_gpio: Fix gpio_set_value() implementation
by Axel Lin 04 Jul '14

04 Jul '14

In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

[U-Boot] [PATCH] Timeout for SDHCI commands
by Eli Billauer 04 Jul '14

04 Jul '14

The patch in the following mail is a result of a problem I had using an eMMC device on a Xilinx Zynq ARM processor. It turned out that the waiting for a certain response from the SDIO interface was made with a plain loop, with no absolute time measurement. Since I'm using a relatively fast processor, the timeout expired before the eMMC chip managed to acknowledge an mmc_switch() with EXT_CSD_HS_TIMING. This patch fixes the problem on my board, and eMMC works properly with it. However I can't say that I really understand what I did, and the 100 ms timeout was chosen with a finger in the wind. If there's a reason why the timeout should be longer or shorter, this is a good time to come forward.
