2020-07-17x86: apl: Set the correct boot mode in the FSP-M codeSimon Glass
If there is MRC information we should run FSP-M with a different boot_mode flag since it is supposed to do a 'fast path' through the memory init. Fix this.

Writing tables is currently pretty opaque. Add a bit of debugging to the process so we can see what tables are written and where they start/end in memory.

2020-07-17x86: apl: Fix save/restore of ITSS prioritiesSimon Glass
The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.

For many device types it is possible to figure out the name just by looking at its uclass or parent. Add a function to handle this, since it allows us to cover the vast majority of cases automatically. However it is sometimes impossible to figure out an ACPI name for a device just by looking at its uclass. For example a touch device may have a vendor-specific name. Add a new "acpi,name" property to allow a custom name to be created. With this new feature we can drop the get_name() methods in the sandbox I2C and SPI drivers.

the DRAM Controller in i.MX8MP will support a feature called "Inline ECC". This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and DDR3L). When this feature is enabled by software, the DRAM Controller reserves 12.5% of DRAM capacity for ECC information, and presents only the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to the rest of the SoC. The DRAM memory can be divided into 8 regions so that if a use case only requires ECC protection on a subset of memory, then only that subset of memory need support inline ECC. If this occurs, then there is no performance penalty accessing the non-ECC-protected memory (no need to access ECC for this portion of the memory map). This is all configured with the DRAM Controller. Signed-off-by: Sherry Sun <sherry.sun@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
