SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts. All of the PCI/PCI-Express driver and initialization code that was in the MPC8641HPCN port has now been moved into the common drivers/fsl_pci_init.c. In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too.

fsl_pci: use 'Header Type' field to judge PCIE mode The original code uses 'Programming Interface' field to judge if PCIE is EP or RC mode, however, T4240 does not support this functionality. According to PCIE specification, 'Header Type' offset 0x0e is used to indicate header type, so for PCIE controller, the patch changes code to use 'Header Type' field to identify if the PCIE is EP or RC mode.

powerpc/fsl-pci: Add generic code to setup PCIe controllers Since all the PCIe controllers are connected over SERDES on the SoCs we can utilize is_serdes_configured() to determine if a controller is enabled. After which we can setup the ATMUs and LAWs for the controller in a common fashion and allow board code to specify what the controller is connected to for reporting reasons. We also provide a per controller (rather than all) for some systems that may have special requirements. Finally, we refactor the code used by the P1022DS to utilize the new generic code.

pci/fsl_pci_init: Rework PCI ATMU setup to handle >4G of memory The old PCI ATMU setup code would just mimic the PCI regions into the ATMU registers. For simple memory maps in which all memory, MMIO, etc space fit into 4G this works ok. However there are issues with we have >4G of memory as we know can't access all of memory and we need to ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with anything since we can't turn it off. We first setup outbound windows based on what the board code setup in the pci regions for MMIO and IO access. Next we place PCICSRBAR below the MMIO window. After which we try to setup the inbound windows to map as much of memory as possible. On PCIe based controllers we are able to overmap the ATMU setup since RX & TX links are separate but report the proper amount of inbound address space to the region tracking to ensure there is no overlap. On PCI based controllers we use as many inbound windows as available to map as much of the memory as possible. Additionally we changed all the CCSR register access to use proper IO accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some 86xx platforms that didn't have it defined.

For simple memory maps in which all memory, MMIO, etc space fit into 4G this works ok. However there are issues with we have >4G of memory as we know can't access all of memory and we need to ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with anything since we can't turn it off. We first setup outbound windows based on what the board code setup in the pci regions for MMIO and IO access. Next we place PCICSRBAR below the MMIO window. After which we try to setup the inbound windows to map as much of memory as possible. On PCIe based controllers we are able to overmap the ATMU setup since RX & TX links are separate but report the proper amount of inbound address space to the region tracking to ensure there is no overlap. On PCI based controllers we use as many inbound windows as available to map as much of the memory as possible. Additionally we changed all the CCSR register access to use proper IO accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some 86xx platforms that didn't have it defined.

powerpc/boot: Change the macro of Boot from SRIO and PCIE master module Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable the master module of Boot from SRIO and PCIE on a platform. But this is not a silicon feature, it's just a specific booting mode based on the SRIO and PCIE interfaces. So it's inappropriate to put the macro into the file arch/powerpc/include/asm/config_mpc85xx.h. Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to "CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros in configuration header file of each board which can support the master module of Boot from SRIO and PCIE.

#ifdef CONFIG_SRIO_PCIE_BOOT_MASTER
powerpc/corenet_ds: Master module for boot from PCIE For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW. The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3. Set outbound windows in order to configure slave's registers for the core's releasing. 4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2" or "PCIE3" using the following command: setenv bootmaster PCIE1 saveenv Signed-off-by: Liu Gang <Gang.Liu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

powerpc/corenet_ds: Master module for boot from PCIE For the powerpc processors with PCIE interface, boot location can be configured from one PCIE interface by RCW. The processor booting from PCIE can do without flash for u-boot image. The image can be fetched from another processor's memory space by PCIE link connected between them. The processor booting from PCIE is slave, the processor booting from normal flash memory space is master, and it can help slave to boot from master's memory space. When boot from PCIE, slave's core should be in holdoff after powered on for some specific requirements. Master will release the slave's core at the right time by PCIE interface. Environment and requirement: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image is in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure PCIE system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to one PCIE interface by RCW. 3. RCW should configure the SerDes, PCIE interfaces correctly. 4. Must set all the cores in holdoff by RCW. 5. Must be powered on before master's boot. For the master module, need to finish these processes: 1. Initialize the PCIE port and address space. 2. Set inbound PCIE windows covered slave's u-boot image stored in master's NOR flash. 3.

Previously, the address of a requested capability is define like that "#define PCI_DCR 0x78" But, the addresses of capabilities is different with regard to PCIe revs. So this method is not flexible. Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1. Read Status register in PCIe configuration space to confirm that Capabilities List is valid. 2. Find the address of Capabilities Pointer Register. 3. Find the address of requested capability from the first capability. Signed-off-by: Zhao Qiang <B45475@freescale.com>

Previously, the address of a requested capability is define like that "#define PCI_DCR 0x78" But, the addresses of capabilities is different with regard to PCIe revs. So this method is not flexible. Now a function to get the address of a requested capability is added and used. It can get the address dynamically by capability ID. The step of this function: 1. Read Status register in PCIe configuration space to confirm that Capabilities List is valid. 2. Find the address of Capabilities Pointer Register. 3.

powerpc/boot: Change the macro of Boot from SRIO and PCIE master module Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable the master module of Boot from SRIO and PCIE on a platform. But this is not a silicon feature, it's just a specific booting mode based on the SRIO and PCIE interfaces. So it's inappropriate to put the macro into the file arch/powerpc/include/asm/config_mpc85xx.h. Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to "CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros in configuration header file of each board which can support the master module of Boot from SRIO and PCIE.

pci/fsl_pci_init: Rework PCI ATMU setup to handle >4G of memory The old PCI ATMU setup code would just mimic the PCI regions into the ATMU registers. For simple memory maps in which all memory, MMIO, etc space fit into 4G this works ok. However there are issues with we have >4G of memory as we know can't access all of memory and we need to ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with anything since we can't turn it off. We first setup outbound windows based on what the board code setup in the pci regions for MMIO and IO access. Next we place PCICSRBAR below the MMIO window. After which we try to setup the inbound windows to map as much of memory as possible. On PCIe based controllers we are able to overmap the ATMU setup since RX & TX links are separate but report the proper amount of inbound address space to the region tracking to ensure there is no overlap. On PCI based controllers we use as many inbound windows as available to map as much of the memory as possible. Additionally we changed all the CCSR register access to use proper IO accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some 86xx platforms that didn't have it defined.

In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too.

Previously boards that did not implement it would print unsightly output such as "PCIE1: Connected to <NULL>..." - Rewords the PCIe boot output to reduce line length and to make it clear that the "base address XYZ" value refers to the base address of the internal processor PCIe registers and not a standard PCI BAR value. - Changes "PCIE" output to the standard "PCIe" Before change: PCIE1: connected to <NULL> as Root Complex (base addr ef008000) 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 05 PCIE2: connected to <NULL> as Endpoint (base addr ef009000) PCIE2: Bus 06 - 06 After change: PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIe1: Bus 00 - 05 PCIe2: Endpoint of VPX Fabric A, x2, regs @ 0xef009000 PCIe2: Bus 06 - 06 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

fsl_pci: Update PCIe boot ouput This change does the following: - Adds printing of negotiated link width. This information can be useful when debugging PCIe issues. - Makes it optional for boards to implement board_serdes_name(). Previously boards that did not implement it would print unsightly output such as "PCIE1: Connected to <NULL>..." - Rewords the PCIe boot output to reduce line length and to make it clear that the "base address XYZ" value refers to the base address of the internal processor PCIe registers and not a standard PCI BAR value. - Changes "PCIE" output to the standard "PCIe" Before change: PCIE1: connected to <NULL> as Root Complex (base addr ef008000) 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 05 PCIE2: connected to <NULL> as Endpoint (base addr ef009000) PCIE2: Bus 06 - 06 After change: PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000 01:00.0 - 10b5:8518 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device PCIe1: Bus 00 - 05 PCIe2: Endpoint of VPX Fabric A, x2, regs @ 0xef009000 PCIe2: Bus 06 - 06 Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

We determine that a controller was not setup (because of HW config) based on the fact that cfg_addr wasn't setup. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

powerpc/85xx & 86xx: Rework ft_fsl_pci_setup to not require aliases Previously we used an alias the pci node to determine which node to fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to find the node to update. Additionally, we replace the code in each board with a single macro call that makes assumes uniform naming and reduces duplication in this area. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
