2022-04-04ARM: ep93xx: enable SPARSE_IRQArnd Bergmann1-1/+2
Without CONFIG_SPARSE_IRQ, we rely on mach/irqs.h to define NR_IRQS globally. Do the minimal conversion by setting .nr_irqs in each machine descriptor. Only the vision_ep9307 machine has extra IRQs for GPIOs, so make .nr_irqs the original value there, while using the plain NR_EP93XX_IRQS everywhere else.

2021-08-04ARM: ep93xx: remove MaverickCrunch supportArnd Bergmann1-2/+0
The MaverickCrunch support for ep93xx never made it into glibc and was removed from gcc in its 4.8 release in 2012. It is now one of the last parts of arch/arm/ that fails to build with the clang integrated assembler, which is unlikely to ever want to support it. The two alternatives are to force the use of binutils/gas when building the crunch support, or to remove it entirely. According to Hartley Sweeten: "Martin Guy did a lot of work trying to get the maverick crunch working but I was never able to successfully use it for anything. It "kind" of works but depending on the EP93xx silicon revision there are still a number of hardware bugs that either give imprecise or garbage results. I have no problem with removing the kernel support for the maverick crunch." Unless someone else comes up with a good reason to keep it around, remove it now. This touches mostly the ep93xx platform, but removes a bit of code from ARM common ptrace and signal frame handling as well. If there are remaining users of MaverickCrunch, they can use LTS kernels for at least another five years before kernel support ends.

This converts the EP93xx SPI master driver to use GPIO descriptors for chip select handling.

Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.

2010-04-14ARM: 5992/1: ep93xx: pass platform startup data as __initdataHartley Sweeten1-1/+1
A number of the peripherals for the ep93xx are registered at startup using platform_data that is passed from the board init code to the core code. This data is then copied to a local static variable in the core code. Since the data is copied, the original data can be marked as __initdata and discarded after startup is complete. This adds the __initdata tag to all the appropriate data in the various ep93xx board init's. Specifically, all the struct ep93xx_eth_data, struct ep93xxfb_mach_info, and struct i2c_gpio_platform_data. Also, document the various registration functions and note what data should be marked as __initdata. While here, also cleanup a couple over zealous whitespace tabs.

Update the NOR flash support for TS-7200. The TS-7200 models all have 16-bit NOR flash. Update the platform init to support this.

arch/arm/mach-ep93xx/include/mach/hardware.h 1. Properly name the include files so that they are loaded from the <mach/*> directory and not the local directory. 2. Remove including the ts72xx.h header. This header is not generic to the ep93xx platform. It should only be included by the ts72xx specific files that require it. The only two users in the tree are arch/arm/mach-ep93xx/ts72xx.c and drivers/mtd/nand/ts7250.c. arch/arm/mach-ep93xx/include/mach/ts72xx.h 1. <linux/io.h> should already be included by any user of this header. Doing the include here hides it from being needed by the calling source file. arch/arm/mach-ep93xx/core.c 1. Remove unnecessary headers. They were probably included originally due to cut-and-paste from other files. 2. <linux/io.h> should be included not <mach/gpio.h> arch/arm/mach-ep93xx/adsphere.c arch/arm/mach-ep93xx/edb93xx.c arch/arm/mach-ep93xx/gesbc9312.c arch/arm/mach-ep93xx/micro9.c arch/arm/mach-ep93xx/ts72xx.c 1. Remove unnecessary headers. arch/arm/mach-ep93xx/ts72xx.c 1. Remove unnecessary headers. 2. Add platform specific header <mach/ts72xx.h>. drivers/mtd/nand/ts7250.c 1. <linux/io.h> should be included not <asm/io.h>. 2. Add platform specific header <mach/ts72xx.h>.
