There are other (non-SDHCI) controllers which supports ADMA2 descriptor tables, namely the Freescale eSDHC. Instead of copying the code, move it into an own module. Signed-off-by:Michael Walle <michael@walle.cc>

First, we need the waterlevel setting for PIO mode only. Secondy, both DMA setup code is identical for both directions, except for the data pointer. Thus, unify them. Signed-off-by: -
Use the dma_{map,unmap}_single() calls. These will take care of the flushing and invalidation of caches. Signed-off-by: -
SDMA can only do DMA with 32 bit addresses. This is true for all architectures (just doesn't apply to 32 bit ones). Simplify the code and remove unnecessary CONFIG_FSL_LAYERSCAPE. Also make the error message more concise. Signed-off-by: -
This 1ms delay before sending command already exist from the beginning of the fsl_esdhc driver added in year 2008. Now this driver has been split for two files: fsl_esdhc.c and fsl_esdhc_imx.c. fsl_esdhc_imx.c only for i.MX series. i.MX series esdhc/usdhc do not need this 1ms delay before sending any command. So remove this 1ms, this will save a lot time if handling a large mmc data. Signed-off-by: -
According to the code logic in __mmc_switch, if the parameter 'send_status' is zero, no need to send cmd13, just wait the stated timeout time, then can return directly. Signed-off-by: -

Add properties related to eMMC HS400 mode. mmc-hs400-1_8v; bus-width = <8>; They had been already in kernel dts file since the first lx2160ardb dts patch. b068890 arm64: dts: add LX2160ARDB board support Signed-off-by: -
There was a fix-up for eMMC HS400 stability issue in Linux. Patch link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/ commit/?id=58d0bf843b49fa99588ac9f85178bd8dfd651b53 Description: Currently only LX2160A eSDHC supports eMMC HS400. According to a large number of tests, eMMC HS400 failed to work at 150MHz, and for a few boards failed to work at 175MHz. But eMMC HS400 worked fine on 200MHz. We hadn't found the root cause but setting eSDHC_DLLCFG0[DLL_FREQ_SEL] = 0 using slow delay chain seemed to resovle this issue. Let's use this as fixup for now. Introduce the fix-up in u-boot since the issue could be reproduced in u-boot too. Signed-off-by:

Fix mmc->clock with actual clock which is divided by the controller, and record it with priv->clock which was removed accidentally. Signed-off-by: -
The process for eMMC HS400 mode for eSDHC is, 1. Perform the Tuning Process at the HS400 target operating frequency. Latched the clock division value. 2. if read transaction, then set the SDTIMNGCTL[FLW_CTL_BG]. 3. Switch to High Speed mode and then set the card clock frequency to a value not greater than 52Mhz 4. Clear TBCTL[TB_EN],tuning block enable bit. 5. Change to 8 bit DDR Mode 6. Switch the card to HS400 mode. 7. Set TBCTL[TB_EN], tuning block enable bit. 8. Clear SYSCTL[SDCLKEN] 9. Wait for PRSSTAT[SDSTB] to be set 10. Change the clock division to latched value.Set TBCTL[HS 400 mode] and Set SDCLKCTL[CMD_CLK_CTRL] 11. Set SYSCTL[SDCLKEN] 12. Wait for PRSSTAT[SDSTB] to be set 13. Set DLLCFG0[DLL_ENABLE] and DLLCFG0[DLL_FREQ_SEL]. 14. Wait for delay chain to lock. 15. Set TBCTL[HS400_WNDW_ADJUST] 16. Again clear SYSCTL[SDCLKEN] 17. Wait for PRSSTAT[SDSTB] to be set 18. Set ESDHCCTL[FAF] 19. Wait for ESDHCCTL[FAF] to be cleared 20. Set SYSCTL[SDCLKEN] 21. Wait for PRSSTAT[SDSTB] to be set. Signed-off-by: -

Some controllers may have difference between HS200 tuning and HS400 tuning, such as different registers setting, different procedure, or different errata. This patch is to add a hs400_tuning flag to identify the tuning for HS400 mode. Signed-off-by: -

Since the previous patch, net_init now exposes some errors, so check for them. Signed-off-by:
Sean Anderson <seanga2@gmail.com> Reviewed-by:
-
net_init does not always succeed, and there is no existing mechanism to discover errors. This patch allows callers of net_init (such as net_init) to handle errors. The root issue is that eth_get_dev can fail, but net_init_loop doesn't expose that. The ideal way to fix eth_get_dev would be to return an error with ERR_PTR, but there are a lot of callers, and all of them just check if it's NULL. Another approach would be to change the signature to something like int eth_get_dev(struct udevice **pdev) but that would require rewriting all of the many callers. Signed-off-by:

This driver interferes with other sandbox tests since it causes log output to be interspersed with "No ethernet found." messages. Disable this driver by default. Enable it for the syslog tests so that they still pass. Signed-off-by: -
At present all log devices are enabled by default. Add a function to allow devices to be disabled or enabled at runtime. Signed-off-by: -
This is not needed as the Makefile only builds the file if CONFIG_LOG_TEST is enabled. Drop it. Signed-off-by: -
At present there is no way to disable a log driver. But the syslog driver causes (attempted) network traffic in sandbox every time a log message is printed, which is often. Add a flag to enable a log driver. Adjust struct log_device to use a short for next_filter_num so that no more memory is used for devices. Also fix a missing line in the struct log_driver comment while here. To maintain compatibility, enable it for all drivers for now. Signed-off-by: -
It is sometimes useful to output hex dumps in SPL. Add a config option to allow this. Signed-off-by:

At present if CONFIG_LOG enabled, putting LOG_DEBUG at the top of a file (before log.h inclusion) causes _log() to be executed for every log() call, regardless of the build- or run-time logging level. However there is no guarantee that the log record will actually be displayed. If the current log level is lower than LOGL_DEBUG then it will not be. Add a way to signal that the log record should always be displayed and update log_passes_filters() to handle this. With the new behaviour, log_debug() will always log if LOG_DEBUG is enabled. Move log_test_syslog_nodebug() into its own file since it cannot be made to work where it is, with LOG_DEBUG defined. Signed-off-by:

At present MKIMAGE_DTC_PATH is in the devicetree menu but not within 'devicetree control' since it does not relate to that. As a result it shows up in the top menu. It actually relates to the mkimage tool, so create a new tools menu for it and move it there. Signed-off-by: -
