[U-Boot] [PATCH] i.MX28: Add function to adjust memory parameters
by Marek Vasut 19 Jun '12

19 Jun '12

This function can be overridden at run-time and allows implementors of new boards based on the i.MX28 chip to fine-tune the memory params. It is possible to write into the dram_vals array because when the SPL runs, it is located SRAM. Therefore the location is writable. There is no possibility of these data to be read-only.

[U-Boot] [PATCH 0/8 V3] EXYNOS5: Enable I2C support
by Rajeshwari Shinde 19 Jun '12

19 Jun '12

This patch set enables I2C support for EXYNOS5. This patchset modifies the s3c24x0 I2C driver to use same for EXYNOS5. Multichannel support has been added to the s3c24x0 I2C driver. s3c24x0_i2c struct has been moved to a common place as it can used by different SOC's. Changes in V2: - Incorporated review comments from Simon Glass. - Aligned the pinmux functionality as per latest comments Changes in V3: - Incorporated review comments from Joonyoung Shim for I2C driver. Rajeshwari Shinde (8): EXYNOS: CLK: Add i2c clock EXYNOS: Add I2C base address. EXYNOS: PINMUX: Add pinmux support for I2C I2C: Move struct s3c24x0_i2c to a common place.

Hi , While surfing , I got the Secure Bootloader patch. But this patch is not integrated with any u-boot source code. Is any reason? Where I get the tarball of entire source code with this patch features.

[U-Boot] Acccessing IRAM in MX53
by Teemu Keskinarkaus 18 Jun '12

18 Jun '12

Hi, I need to access IRAM from U-boot in MX53 based HW. This is part of the data transfer between kernel and U-boot. I've already done the kernel part and now I need to do the U-boot part. I tried this: #define IRAM_ADDRESS IRAM_BASE_ADDR + IRAM_SIZE - SZ_4K unsigned long *iram = (unsigned long*)IRAM_ADDRESS; unsigned long data; data = *iram; But with that code the U-boot just gets stuck when trying to access the IRAM. I looked and it seems that IRAM is added to MMU definitions and virtual address is the same as physical. So questions is. How should I access the IRAM if the method I'm using is not correct or what's wrong in my method? Teemu Keskinarkaus
