| | | | | | | | | | | This problem is found when debugging QuadSPI. When "A" bit is enabled, unaligned access will cause data abort exception. Actually, we do not want this exception. So clear the align bit for MX6 SOCs. Tested this code with android team colleague and did not find problem.

* MLK-10504 imx: mx6dqarm2: Fix CCM setting for lpddr2 400Mhz supportYe.Li2015-04-29-0/+6
| | | | | | | | | | | | | | | | | | Current uboot supports for running LPDDR2 at 400MHz on MX6Q ARM2 board, but there is a problem in switching pre_periph_clk_sel to pll2_pfd2. We cannot directly change the parent of pre_periph_clk_sel as this mux is not a glitchless mux. We need to follow the correct procedure and wait for the busy bits to clear before switching. Change to follow the procedure: 1. Set periph_clk2 to OSC. 2. Switch the periph_clk to periph_clk2, checking the CCM_CDHIPR for periph_clk , ahb_podf and axi_podf busy bits. 3. Setting the pre_periph_clk to PLL2 PFD 396M. 4. Switch the periph_clk back to pre_periph_clk and checking CCM_CDHIPR busy bits.

* MLK-10647 armv7: Fix Dcache disable issue on i.MX7Ye.Li2015-04-29-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The issue on the i.MX7D is that, there is one cache-able memory access between the L1 and L2 cache flush by calling the flush_dache_all-> v7_maint_dcache_all() [Flush L1 and L2 cache) which written in the C code. L1-cache-flush -> This will flush L1 cache to L2 cache in the end. Cache-able memory access -> This will have the chance cause the L1 line-fill with dirty data from L2 cache(L1 cache-line dirty, L2 clean) L2-cache-flush -> This will only flush L2 cache to L3, but still some dirty data on the L1 cacheline. After C & M bit clean, -> The dirty data on the L1 cache line lost, which will cause memory coherent issue if that dirty cache line has some useful data The only problem here is: there is one cache-cable memory access between L1 and L2 cache flush. This patch should works fine on the i.MX6 and i.MX7. The second cache flush have zero impact on the i.MX6, but this is really need for the i.MX7D platform due to the L1 line-fill during the first dcache_flush. And the second flush will not bring in the L1 dirty cache line due to the C bit is clear now, which means the dcache is disabled.

* MLK-10467 mtd:spi Add ATMEL AT45DB021E supportPeng Fan2015-04-29-2/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add atmel AT45DB021E spi flash support. Since this flash is different from the spi flash that we previous use such as m25p32 and spanion spi nor flashes, pieces of code are added. 1. The default page size is 264 bytes, but the mtd/spi framework can not handle such page. So we need to configure the page size from 264 to 256 bytes. Page Size command seq “Power of 2” binary page size (256 bytes)| 3Dh 2Ah 80h A6h DataFlash page size (264 bytes) | 3Dh 2Ah 80h A7h And when probe the flash, configure the flash to 256 bytes page size, if the page size is already 256bytes, just return and do not configure it again. The page size configuration times is only about 10000, so to avoid configuring it each time. 2. Add the flash params in sf_params.c. 3. This flash support 2K block erase, add this flag. 4. The status command is 0xD7, different from others. It's polling status bit is Bit 7 -> 0 Device is busy with an internal operation. -> 1 Device is ready. This patch has been tested on mx7d 19x19 ddr3 arm2 board. And tested on mx7d 12x12 lpddr3 board. All works fine. Note: Since this flash is only 256KB, we can not test spi boot on mx7d 19x19 arm2 board. If want to test this flash, open CONFIG_SYS_USE_SPINOR.
